Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105538, here are decompositions:

  • 5 + 105533 = 105538
  • 11 + 105527 = 105538
  • 29 + 105509 = 105538
  • 47 + 105491 = 105538
  • 71 + 105467 = 105538
  • 89 + 105449 = 105538
  • 101 + 105437 = 105538
  • 131 + 105407 = 105538

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 105,538 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 105538 first appears in π at position 581,137 of the decimal expansion (the 581,137ordinal-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.
