Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471576, here are decompositions:

  • 53 + 31471523 = 31471576
  • 107 + 31471469 = 31471576
  • 137 + 31471439 = 31471576
  • 179 + 31471397 = 31471576
  • 359 + 31471217 = 31471576
  • 467 + 31471109 = 31471576
  • 569 + 31471007 = 31471576
  • 599 + 31470977 = 31471576

Showing the first eight; more decompositions exist.
