Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143808, here are decompositions:

  • 11 + 143797 = 143808
  • 17 + 143791 = 143808
  • 29 + 143779 = 143808
  • 79 + 143729 = 143808
  • 89 + 143719 = 143808
  • 97 + 143711 = 143808
  • 109 + 143699 = 143808
  • 131 + 143677 = 143808

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 143,808 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 143808 first appears in π at position 107,954 of the decimal expansion (the 107,954ordinal-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.
