Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66546, here are decompositions:

  • 5 + 66541 = 66546
  • 13 + 66533 = 66546
  • 17 + 66529 = 66546
  • 23 + 66523 = 66546
  • 37 + 66509 = 66546
  • 47 + 66499 = 66546
  • 79 + 66467 = 66546
  • 83 + 66463 = 66546

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66546 first appears in π at position 140,536 of the decimal expansion (the 140,536ordinal-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.
