Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545604, here are decompositions:

  • 5 + 31545599 = 31545604
  • 197 + 31545407 = 31545604
  • 281 + 31545323 = 31545604
  • 317 + 31545287 = 31545604
  • 383 + 31545221 = 31545604
  • 521 + 31545083 = 31545604
  • 641 + 31544963 = 31545604
  • 821 + 31544783 = 31545604

Showing the first eight; more decompositions exist.
