Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151948, here are decompositions:

  • 11 + 151937 = 151948
  • 47 + 151901 = 151948
  • 101 + 151847 = 151948
  • 107 + 151841 = 151948
  • 131 + 151817 = 151948
  • 149 + 151799 = 151948
  • 179 + 151769 = 151948
  • 281 + 151667 = 151948

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 151,948 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 151948 first appears in π at position 309,739 of the decimal expansion (the 309,739ordinal-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.
