Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466278, here are decompositions:

  • 29 + 31466249 = 31466278
  • 71 + 31466207 = 31466278
  • 227 + 31466051 = 31466278
  • 449 + 31465829 = 31466278
  • 521 + 31465757 = 31466278
  • 617 + 31465661 = 31466278
  • 647 + 31465631 = 31466278
  • 659 + 31465619 = 31466278

Showing the first eight; more decompositions exist.
