Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105126, here are decompositions:

  • 19 + 105107 = 105126
  • 29 + 105097 = 105126
  • 89 + 105037 = 105126
  • 103 + 105023 = 105126
  • 107 + 105019 = 105126
  • 127 + 104999 = 105126
  • 139 + 104987 = 105126
  • 167 + 104959 = 105126

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 105,126 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 105126 first appears in π at position 730,760 of the decimal expansion (the 730,760ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
