Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464730, here are decompositions:

  • 29 + 31464701 = 31464730
  • 113 + 31464617 = 31464730
  • 149 + 31464581 = 31464730
  • 173 + 31464557 = 31464730
  • 389 + 31464341 = 31464730
  • 449 + 31464281 = 31464730
  • 461 + 31464269 = 31464730
  • 587 + 31464143 = 31464730

Showing the first eight; more decompositions exist.
