Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526550, here are decompositions:

  • 17 + 31526533 = 31526550
  • 23 + 31526527 = 31526550
  • 47 + 31526503 = 31526550
  • 53 + 31526497 = 31526550
  • 61 + 31526489 = 31526550
  • 73 + 31526477 = 31526550
  • 127 + 31526423 = 31526550
  • 131 + 31526419 = 31526550

Showing the first eight; more decompositions exist.
