Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455350, here are decompositions:

  • 37 + 31455313 = 31455350
  • 79 + 31455271 = 31455350
  • 127 + 31455223 = 31455350
  • 211 + 31455139 = 31455350
  • 229 + 31455121 = 31455350
  • 379 + 31454971 = 31455350
  • 397 + 31454953 = 31455350
  • 523 + 31454827 = 31455350

Showing the first eight; more decompositions exist.
