Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154566, here are decompositions:

  • 23 + 154543 = 154566
  • 43 + 154523 = 154566
  • 73 + 154493 = 154566
  • 79 + 154487 = 154566
  • 107 + 154459 = 154566
  • 127 + 154439 = 154566
  • 149 + 154417 = 154566
  • 157 + 154409 = 154566

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 154,566 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 154566 first appears in π at position 157,243 of the decimal expansion (the 157,243ordinal-suffix:rd 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.
