Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522760, here are decompositions:

  • 13 + 31522747 = 31522760
  • 43 + 31522717 = 31522760
  • 67 + 31522693 = 31522760
  • 97 + 31522663 = 31522760
  • 103 + 31522657 = 31522760
  • 127 + 31522633 = 31522760
  • 163 + 31522597 = 31522760
  • 211 + 31522549 = 31522760

Showing the first eight; more decompositions exist.
