Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102928, here are decompositions:

  • 17 + 102911 = 102928
  • 47 + 102881 = 102928
  • 131 + 102797 = 102928
  • 167 + 102761 = 102928
  • 227 + 102701 = 102928
  • 251 + 102677 = 102928
  • 281 + 102647 = 102928
  • 317 + 102611 = 102928

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 102,928 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 102928 first appears in π at position 307,167 of the decimal expansion (the 307,167ordinal-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.
