Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72396, here are decompositions:

  • 13 + 72383 = 72396
  • 17 + 72379 = 72396
  • 29 + 72367 = 72396
  • 43 + 72353 = 72396
  • 59 + 72337 = 72396
  • 83 + 72313 = 72396
  • 89 + 72307 = 72396
  • 109 + 72287 = 72396

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 72396 first appears in π at position 6,644 of the decimal expansion (the 6,644ordinal-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.
