Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613722, here are decompositions:

  • 3 + 31613719 = 31613722
  • 5 + 31613717 = 31613722
  • 53 + 31613669 = 31613722
  • 83 + 31613639 = 31613722
  • 281 + 31613441 = 31613722
  • 311 + 31613411 = 31613722
  • 389 + 31613333 = 31613722
  • 431 + 31613291 = 31613722

Showing the first eight; more decompositions exist.
