Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545362, here are decompositions:

  • 19 + 31545343 = 31545362
  • 31 + 31545331 = 31545362
  • 151 + 31545211 = 31545362
  • 181 + 31545181 = 31545362
  • 271 + 31545091 = 31545362
  • 313 + 31545049 = 31545362
  • 421 + 31544941 = 31545362
  • 439 + 31544923 = 31545362

Showing the first eight; more decompositions exist.
