Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545494, here are decompositions:

  • 7 + 31545487 = 31545494
  • 103 + 31545391 = 31545494
  • 151 + 31545343 = 31545494
  • 163 + 31545331 = 31545494
  • 283 + 31545211 = 31545494
  • 313 + 31545181 = 31545494
  • 397 + 31545097 = 31545494
  • 433 + 31545061 = 31545494

Showing the first eight; more decompositions exist.
