Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103100, here are decompositions:

  • 7 + 103093 = 103100
  • 13 + 103087 = 103100
  • 31 + 103069 = 103100
  • 223 + 102877 = 103100
  • 229 + 102871 = 103100
  • 241 + 102859 = 103100
  • 271 + 102829 = 103100
  • 307 + 102793 = 103100

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 103,100 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 103100 first appears in π at position 12,099 of the decimal expansion (the 12,099ordinal-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.
