Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109638, here are decompositions:

  • 17 + 109621 = 109638
  • 19 + 109619 = 109638
  • 29 + 109609 = 109638
  • 41 + 109597 = 109638
  • 59 + 109579 = 109638
  • 71 + 109567 = 109638
  • 97 + 109541 = 109638
  • 101 + 109537 = 109638

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 109,638 and was likely granted around 1871.

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

Position in π

The digit sequence 109638 first appears in π at position 53,250 of the decimal expansion (the 53,250ordinal-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.
