Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103800, here are decompositions:

  • 13 + 103787 = 103800
  • 31 + 103769 = 103800
  • 97 + 103703 = 103800
  • 101 + 103699 = 103800
  • 113 + 103687 = 103800
  • 131 + 103669 = 103800
  • 149 + 103651 = 103800
  • 157 + 103643 = 103800

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 103,800 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 103800 first appears in π at position 474,750 of the decimal expansion (the 474,750ordinal-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.
