Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542576, here are decompositions:

  • 17 + 31542559 = 31542576
  • 29 + 31542547 = 31542576
  • 53 + 31542523 = 31542576
  • 67 + 31542509 = 31542576
  • 89 + 31542487 = 31542576
  • 97 + 31542479 = 31542576
  • 137 + 31542439 = 31542576
  • 139 + 31542437 = 31542576

Showing the first eight; more decompositions exist.
