Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163554, here are decompositions:

  • 11 + 163543 = 163554
  • 37 + 163517 = 163554
  • 67 + 163487 = 163554
  • 71 + 163483 = 163554
  • 73 + 163481 = 163554
  • 137 + 163417 = 163554
  • 151 + 163403 = 163554
  • 191 + 163363 = 163554

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 163,554 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 163554 first appears in π at position 299,156 of the decimal expansion (the 299,156ordinal-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.
