Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105618, here are decompositions:

  • 5 + 105613 = 105618
  • 11 + 105607 = 105618
  • 17 + 105601 = 105618
  • 61 + 105557 = 105618
  • 89 + 105529 = 105618
  • 101 + 105517 = 105618
  • 109 + 105509 = 105618
  • 127 + 105491 = 105618

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 105,618 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 105618 first appears in π at position 89,856 of the decimal expansion (the 89,856ordinal-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.
