Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7272, here are decompositions:

  • 19 + 7253 = 7272
  • 29 + 7243 = 7272
  • 43 + 7229 = 7272
  • 53 + 7219 = 7272
  • 59 + 7213 = 7272
  • 61 + 7211 = 7272
  • 79 + 7193 = 7272
  • 113 + 7159 = 7272

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7272 first appears in π at position 30,522 of the decimal expansion (the 30,522ordinal-suffix:nd 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.
