Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154800, here are decompositions:

  • 11 + 154789 = 154800
  • 13 + 154787 = 154800
  • 31 + 154769 = 154800
  • 47 + 154753 = 154800
  • 53 + 154747 = 154800
  • 67 + 154733 = 154800
  • 73 + 154727 = 154800
  • 101 + 154699 = 154800

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 154,800 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 154800 first appears in π at position 706,679 of the decimal expansion (the 706,679ordinal-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.
