Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102906, here are decompositions:

  • 29 + 102877 = 102906
  • 47 + 102859 = 102906
  • 109 + 102797 = 102906
  • 113 + 102793 = 102906
  • 137 + 102769 = 102906
  • 227 + 102679 = 102906
  • 229 + 102677 = 102906
  • 233 + 102673 = 102906

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 102,906 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 102906 first appears in π at position 161,246 of the decimal expansion (the 161,246ordinal-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.
