Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164740, here are decompositions:

  • 11 + 164729 = 164740
  • 113 + 164627 = 164740
  • 227 + 164513 = 164740
  • 263 + 164477 = 164740
  • 269 + 164471 = 164740
  • 293 + 164447 = 164740
  • 311 + 164429 = 164740
  • 353 + 164387 = 164740

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 164,740 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 164740 first appears in π at position 483,141 of the decimal expansion (the 483,141ordinal-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.
