Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549000, here are decompositions:

  • 3 + 31548997 = 31549000
  • 17 + 31548983 = 31549000
  • 47 + 31548953 = 31549000
  • 233 + 31548767 = 31549000
  • 251 + 31548749 = 31549000
  • 257 + 31548743 = 31549000
  • 347 + 31548653 = 31549000
  • 359 + 31548641 = 31549000

Showing the first eight; more decompositions exist.
