Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150840, here are decompositions:

  • 7 + 150833 = 150840
  • 13 + 150827 = 150840
  • 43 + 150797 = 150840
  • 61 + 150779 = 150840
  • 71 + 150769 = 150840
  • 73 + 150767 = 150840
  • 97 + 150743 = 150840
  • 181 + 150659 = 150840

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 150,840 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 150840 first appears in π at position 263,336 of the decimal expansion (the 263,336ordinal-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.
