Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82040, here are decompositions:

  • 3 + 82037 = 82040
  • 19 + 82021 = 82040
  • 31 + 82009 = 82040
  • 37 + 82003 = 82040
  • 67 + 81973 = 82040
  • 73 + 81967 = 82040
  • 97 + 81943 = 82040
  • 103 + 81937 = 82040

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 82040 first appears in π at position 19,770 of the decimal expansion (the 19,770ordinal-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.
