Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100100, here are decompositions:

  • 31 + 100069 = 100100
  • 43 + 100057 = 100100
  • 97 + 100003 = 100100
  • 109 + 99991 = 100100
  • 139 + 99961 = 100100
  • 193 + 99907 = 100100
  • 199 + 99901 = 100100
  • 223 + 99877 = 100100

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 100,100 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 100100 first appears in π at position 334,095 of the decimal expansion (the 334,095ordinal-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.
