Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545436, here are decompositions:

  • 7 + 545429 = 545436
  • 107 + 545329 = 545436
  • 179 + 545257 = 545436
  • 197 + 545239 = 545436
  • 223 + 545213 = 545436
  • 233 + 545203 = 545436
  • 293 + 545143 = 545436
  • 347 + 545089 = 545436

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 545,436 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 545436 first appears in π at position 738,493 of the decimal expansion (the 738,493ordinal-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.
