Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498802, here are decompositions:

  • 61 + 31498741 = 31498802
  • 163 + 31498639 = 31498802
  • 211 + 31498591 = 31498802
  • 331 + 31498471 = 31498802
  • 523 + 31498279 = 31498802
  • 613 + 31498189 = 31498802
  • 691 + 31498111 = 31498802
  • 733 + 31498069 = 31498802

Showing the first eight; more decompositions exist.
