Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528388, here are decompositions:

  • 61 + 31528327 = 31528388
  • 97 + 31528291 = 31528388
  • 109 + 31528279 = 31528388
  • 181 + 31528207 = 31528388
  • 277 + 31528111 = 31528388
  • 421 + 31527967 = 31528388
  • 457 + 31527931 = 31528388
  • 571 + 31527817 = 31528388

Showing the first eight; more decompositions exist.
