Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143224, here are decompositions:

  • 47 + 143177 = 143224
  • 83 + 143141 = 143224
  • 113 + 143111 = 143224
  • 131 + 143093 = 143224
  • 251 + 142973 = 143224
  • 317 + 142907 = 143224
  • 353 + 142871 = 143224
  • 383 + 142841 = 143224

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 143,224 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 143224 first appears in π at position 94,486 of the decimal expansion (the 94,486ordinal-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.
