Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547670, here are decompositions:

  • 29 + 31547641 = 31547670
  • 41 + 31547629 = 31547670
  • 53 + 31547617 = 31547670
  • 61 + 31547609 = 31547670
  • 79 + 31547591 = 31547670
  • 113 + 31547557 = 31547670
  • 131 + 31547539 = 31547670
  • 139 + 31547531 = 31547670

Showing the first eight; more decompositions exist.
