Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142548, here are decompositions:

  • 5 + 142543 = 142548
  • 11 + 142537 = 142548
  • 19 + 142529 = 142548
  • 47 + 142501 = 142548
  • 79 + 142469 = 142548
  • 127 + 142421 = 142548
  • 157 + 142391 = 142548
  • 167 + 142381 = 142548

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 142,548 and was likely granted around 1872.

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

Position in π

The digit sequence 142548 first appears in π at position 4,583 of the decimal expansion (the 4,583ordinal-suffix:rd 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.
