Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151798, here are decompositions:

  • 11 + 151787 = 151798
  • 29 + 151769 = 151798
  • 131 + 151667 = 151798
  • 167 + 151631 = 151798
  • 191 + 151607 = 151798
  • 281 + 151517 = 151798
  • 347 + 151451 = 151798
  • 401 + 151397 = 151798

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 151,798 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 151798 first appears in π at position 776,107 of the decimal expansion (the 776,107ordinal-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.
