Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545426, here are decompositions:

  • 19 + 31545407 = 31545426
  • 47 + 31545379 = 31545426
  • 53 + 31545373 = 31545426
  • 83 + 31545343 = 31545426
  • 97 + 31545329 = 31545426
  • 103 + 31545323 = 31545426
  • 109 + 31545317 = 31545426
  • 127 + 31545299 = 31545426

Showing the first eight; more decompositions exist.
