Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445594, here are decompositions:

  • 7 + 31445587 = 31445594
  • 151 + 31445443 = 31445594
  • 163 + 31445431 = 31445594
  • 241 + 31445353 = 31445594
  • 331 + 31445263 = 31445594
  • 373 + 31445221 = 31445594
  • 421 + 31445173 = 31445594
  • 457 + 31445137 = 31445594

Showing the first eight; more decompositions exist.
