Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144154, here are decompositions:

  • 83 + 144071 = 144154
  • 173 + 143981 = 144154
  • 281 + 143873 = 144154
  • 347 + 143807 = 144154
  • 443 + 143711 = 144154
  • 467 + 143687 = 144154
  • 503 + 143651 = 144154
  • 587 + 143567 = 144154

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 144,154 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 144154 first appears in π at position 334,292 of the decimal expansion (the 334,292ordinal-suffix:nd 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.
