Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105400, here are decompositions:

  • 3 + 105397 = 105400
  • 11 + 105389 = 105400
  • 41 + 105359 = 105400
  • 59 + 105341 = 105400
  • 131 + 105269 = 105400
  • 137 + 105263 = 105400
  • 149 + 105251 = 105400
  • 173 + 105227 = 105400

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 105,400 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 105400 first appears in π at position 556,107 of the decimal expansion (the 556,107ordinal-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.
