Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613284, here are decompositions:

  • 41 + 31613243 = 31613284
  • 113 + 31613171 = 31613284
  • 167 + 31613117 = 31613284
  • 257 + 31613027 = 31613284
  • 293 + 31612991 = 31613284
  • 431 + 31612853 = 31613284
  • 557 + 31612727 = 31613284
  • 617 + 31612667 = 31613284

Showing the first eight; more decompositions exist.
