Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30836, here are decompositions:

  • 7 + 30829 = 30836
  • 19 + 30817 = 30836
  • 73 + 30763 = 30836
  • 79 + 30757 = 30836
  • 109 + 30727 = 30836
  • 139 + 30697 = 30836
  • 193 + 30643 = 30836
  • 199 + 30637 = 30836

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30836 first appears in π at position 168,344 of the decimal expansion (the 168,344ordinal-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.
