Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103886, here are decompositions:

  • 19 + 103867 = 103886
  • 43 + 103843 = 103886
  • 73 + 103813 = 103886
  • 163 + 103723 = 103886
  • 199 + 103687 = 103886
  • 229 + 103657 = 103886
  • 313 + 103573 = 103886
  • 337 + 103549 = 103886

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 103,886 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 103886 first appears in π at position 489,800 of the decimal expansion (the 489,800ordinal-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.
