Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103218, here are decompositions:

  • 41 + 103177 = 103218
  • 47 + 103171 = 103218
  • 127 + 103091 = 103218
  • 131 + 103087 = 103218
  • 139 + 103079 = 103218
  • 149 + 103069 = 103218
  • 151 + 103067 = 103218
  • 211 + 103007 = 103218

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 103,218 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 103218 first appears in π at position 629,664 of the decimal expansion (the 629,664ordinal-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.
