Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144752, here are decompositions:

  • 43 + 144709 = 144752
  • 163 + 144589 = 144752
  • 211 + 144541 = 144752
  • 241 + 144511 = 144752
  • 271 + 144481 = 144752
  • 313 + 144439 = 144752
  • 373 + 144379 = 144752
  • 463 + 144289 = 144752

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 144,752 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 144752 first appears in π at position 857,431 of the decimal expansion (the 857,431ordinal-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.
