Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152870, here are decompositions:

  • 13 + 152857 = 152870
  • 19 + 152851 = 152870
  • 31 + 152839 = 152870
  • 37 + 152833 = 152870
  • 61 + 152809 = 152870
  • 79 + 152791 = 152870
  • 103 + 152767 = 152870
  • 199 + 152671 = 152870

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 152,870 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 152870 first appears in π at position 306,874 of the decimal expansion (the 306,874ordinal-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.
