Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144018, here are decompositions:

  • 5 + 144013 = 144018
  • 19 + 143999 = 144018
  • 37 + 143981 = 144018
  • 41 + 143977 = 144018
  • 47 + 143971 = 144018
  • 71 + 143947 = 144018
  • 109 + 143909 = 144018
  • 137 + 143881 = 144018

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 144,018 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 144018 first appears in π at position 891,740 of the decimal expansion (the 891,740ordinal-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.
