Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144858, here are decompositions:

  • 11 + 144847 = 144858
  • 19 + 144839 = 144858
  • 29 + 144829 = 144858
  • 41 + 144817 = 144858
  • 67 + 144791 = 144858
  • 79 + 144779 = 144858
  • 101 + 144757 = 144858
  • 107 + 144751 = 144858

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 144,858 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 144858 first appears in π at position 499,662 of the decimal expansion (the 499,662ordinal-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.
