Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545546, here are decompositions:

  • 47 + 31545499 = 31545546
  • 59 + 31545487 = 31545546
  • 107 + 31545439 = 31545546
  • 139 + 31545407 = 31545546
  • 167 + 31545379 = 31545546
  • 173 + 31545373 = 31545546
  • 223 + 31545323 = 31545546
  • 229 + 31545317 = 31545546

Showing the first eight; more decompositions exist.
