Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465270, here are decompositions:

  • 47 + 31465223 = 31465270
  • 443 + 31464827 = 31465270
  • 449 + 31464821 = 31465270
  • 461 + 31464809 = 31465270
  • 569 + 31464701 = 31465270
  • 653 + 31464617 = 31465270
  • 761 + 31464509 = 31465270
  • 827 + 31464443 = 31465270

Showing the first eight; more decompositions exist.
