Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30982, here are decompositions:

  • 5 + 30977 = 30982
  • 11 + 30971 = 30982
  • 41 + 30941 = 30982
  • 71 + 30911 = 30982
  • 89 + 30893 = 30982
  • 101 + 30881 = 30982
  • 113 + 30869 = 30982
  • 131 + 30851 = 30982

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30982 first appears in π at position 477,458 of the decimal expansion (the 477,458ordinal-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.
