Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545360, here are decompositions:

  • 31 + 545329 = 545360
  • 103 + 545257 = 545360
  • 157 + 545203 = 545360
  • 199 + 545161 = 545360
  • 229 + 545131 = 545360
  • 271 + 545089 = 545360
  • 331 + 545029 = 545360
  • 337 + 545023 = 545360

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 545,360 and was likely granted around 1895.

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

Position in π

The digit sequence 545360 first appears in π at position 459,661 of the decimal expansion (the 459,661ordinal-suffix:st 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.
