Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12450, here are decompositions:

  • 13 + 12437 = 12450
  • 17 + 12433 = 12450
  • 29 + 12421 = 12450
  • 37 + 12413 = 12450
  • 41 + 12409 = 12450
  • 59 + 12391 = 12450
  • 71 + 12379 = 12450
  • 73 + 12377 = 12450

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 12450 first appears in π at position 30,588 of the decimal expansion (the 30,588ordinal-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.
