Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540832, here are decompositions:

  • 19 + 31540813 = 31540832
  • 109 + 31540723 = 31540832
  • 139 + 31540693 = 31540832
  • 163 + 31540669 = 31540832
  • 181 + 31540651 = 31540832
  • 331 + 31540501 = 31540832
  • 523 + 31540309 = 31540832
  • 571 + 31540261 = 31540832

Showing the first eight; more decompositions exist.
