Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626532, here are decompositions:

  • 71 + 31626461 = 31626532
  • 149 + 31626383 = 31626532
  • 173 + 31626359 = 31626532
  • 401 + 31626131 = 31626532
  • 479 + 31626053 = 31626532
  • 491 + 31626041 = 31626532
  • 521 + 31626011 = 31626532
  • 563 + 31625969 = 31626532

Showing the first eight; more decompositions exist.
