Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146666, here are decompositions:

  • 19 + 146647 = 146666
  • 103 + 146563 = 146666
  • 127 + 146539 = 146666
  • 139 + 146527 = 146666
  • 229 + 146437 = 146666
  • 277 + 146389 = 146666
  • 283 + 146383 = 146666
  • 307 + 146359 = 146666

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 146,666 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 146666 first appears in π at position 951,584 of the decimal expansion (the 951,584ordinal-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.
