Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105558, here are decompositions:

  • 17 + 105541 = 105558
  • 29 + 105529 = 105558
  • 31 + 105527 = 105558
  • 41 + 105517 = 105558
  • 59 + 105499 = 105558
  • 67 + 105491 = 105558
  • 109 + 105449 = 105558
  • 151 + 105407 = 105558

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 105,558 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 105558 first appears in π at position 153,925 of the decimal expansion (the 153,925ordinal-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.
