Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525776, here are decompositions:

  • 5 + 31525771 = 31525776
  • 13 + 31525763 = 31525776
  • 53 + 31525723 = 31525776
  • 59 + 31525717 = 31525776
  • 89 + 31525687 = 31525776
  • 127 + 31525649 = 31525776
  • 167 + 31525609 = 31525776
  • 173 + 31525603 = 31525776

Showing the first eight; more decompositions exist.
