Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30744, here are decompositions:

  • 17 + 30727 = 30744
  • 31 + 30713 = 30744
  • 37 + 30707 = 30744
  • 41 + 30703 = 30744
  • 47 + 30697 = 30744
  • 67 + 30677 = 30744
  • 73 + 30671 = 30744
  • 83 + 30661 = 30744

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30744 first appears in π at position 264,846 of the decimal expansion (the 264,846ordinal-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.
