Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146578, here are decompositions:

  • 59 + 146519 = 146578
  • 101 + 146477 = 146578
  • 197 + 146381 = 146578
  • 269 + 146309 = 146578
  • 281 + 146297 = 146578
  • 461 + 146117 = 146578
  • 479 + 146099 = 146578
  • 521 + 146057 = 146578

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 146,578 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 146578 first appears in π at position 27,472 of the decimal expansion (the 27,472ordinal-suffix:nd 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.
