Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545422, here are decompositions:

  • 31 + 31545391 = 31545422
  • 43 + 31545379 = 31545422
  • 79 + 31545343 = 31545422
  • 211 + 31545211 = 31545422
  • 241 + 31545181 = 31545422
  • 331 + 31545091 = 31545422
  • 373 + 31545049 = 31545422
  • 421 + 31545001 = 31545422

Showing the first eight; more decompositions exist.
