Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495802, here are decompositions:

  • 61 + 31495741 = 31495802
  • 73 + 31495729 = 31495802
  • 109 + 31495693 = 31495802
  • 139 + 31495663 = 31495802
  • 199 + 31495603 = 31495802
  • 211 + 31495591 = 31495802
  • 379 + 31495423 = 31495802
  • 631 + 31495171 = 31495802

Showing the first eight; more decompositions exist.
