Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72422, here are decompositions:

  • 43 + 72379 = 72422
  • 109 + 72313 = 72422
  • 151 + 72271 = 72422
  • 193 + 72229 = 72422
  • 199 + 72223 = 72422
  • 211 + 72211 = 72422
  • 283 + 72139 = 72422
  • 313 + 72109 = 72422

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 72422 first appears in π at position 5,055 of the decimal expansion (the 5,055ordinal-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.
