Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528126, here are decompositions:

  • 5 + 31528121 = 31528126
  • 23 + 31528103 = 31528126
  • 59 + 31528067 = 31528126
  • 89 + 31528037 = 31528126
  • 107 + 31528019 = 31528126
  • 239 + 31527887 = 31528126
  • 449 + 31527677 = 31528126
  • 467 + 31527659 = 31528126

Showing the first eight; more decompositions exist.
