Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617752, here are decompositions:

  • 73 + 31617679 = 31617752
  • 79 + 31617673 = 31617752
  • 193 + 31617559 = 31617752
  • 223 + 31617529 = 31617752
  • 349 + 31617403 = 31617752
  • 373 + 31617379 = 31617752
  • 379 + 31617373 = 31617752
  • 499 + 31617253 = 31617752

Showing the first eight; more decompositions exist.
