Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523076, here are decompositions:

  • 23 + 31523053 = 31523076
  • 73 + 31523003 = 31523076
  • 89 + 31522987 = 31523076
  • 97 + 31522979 = 31523076
  • 139 + 31522937 = 31523076
  • 229 + 31522847 = 31523076
  • 359 + 31522717 = 31523076
  • 383 + 31522693 = 31523076

Showing the first eight; more decompositions exist.
