Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527822, here are decompositions:

  • 5 + 31527817 = 31527822
  • 41 + 31527781 = 31527822
  • 113 + 31527709 = 31527822
  • 163 + 31527659 = 31527822
  • 239 + 31527583 = 31527822
  • 281 + 31527541 = 31527822
  • 331 + 31527491 = 31527822
  • 409 + 31527413 = 31527822

Showing the first eight; more decompositions exist.
