Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72036, here are decompositions:

  • 5 + 72031 = 72036
  • 17 + 72019 = 72036
  • 37 + 71999 = 72036
  • 43 + 71993 = 72036
  • 53 + 71983 = 72036
  • 73 + 71963 = 72036
  • 89 + 71947 = 72036
  • 103 + 71933 = 72036

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 72036 first appears in π at position 115,087 of the decimal expansion (the 115,087ordinal-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.
