Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528776, here are decompositions:

  • 47 + 31528729 = 31528776
  • 53 + 31528723 = 31528776
  • 79 + 31528697 = 31528776
  • 107 + 31528669 = 31528776
  • 163 + 31528613 = 31528776
  • 197 + 31528579 = 31528776
  • 229 + 31528547 = 31528776
  • 277 + 31528499 = 31528776

Showing the first eight; more decompositions exist.
