Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448760, here are decompositions:

  • 19 + 31448741 = 31448760
  • 41 + 31448719 = 31448760
  • 43 + 31448717 = 31448760
  • 47 + 31448713 = 31448760
  • 53 + 31448707 = 31448760
  • 61 + 31448699 = 31448760
  • 67 + 31448693 = 31448760
  • 113 + 31448647 = 31448760

Showing the first eight; more decompositions exist.
