Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595760, here are decompositions:

  • 29 + 31595731 = 31595760
  • 37 + 31595723 = 31595760
  • 41 + 31595719 = 31595760
  • 43 + 31595717 = 31595760
  • 59 + 31595701 = 31595760
  • 73 + 31595687 = 31595760
  • 89 + 31595671 = 31595760
  • 103 + 31595657 = 31595760

Showing the first eight; more decompositions exist.
