Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450448, here are decompositions:

  • 19 + 31450429 = 31450448
  • 37 + 31450411 = 31450448
  • 61 + 31450387 = 31450448
  • 79 + 31450369 = 31450448
  • 97 + 31450351 = 31450448
  • 157 + 31450291 = 31450448
  • 229 + 31450219 = 31450448
  • 241 + 31450207 = 31450448

Showing the first eight; more decompositions exist.
