Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623316, here are decompositions:

  • 59 + 31623257 = 31623316
  • 107 + 31623209 = 31623316
  • 149 + 31623167 = 31623316
  • 269 + 31623047 = 31623316
  • 293 + 31623023 = 31623316
  • 383 + 31622933 = 31623316
  • 479 + 31622837 = 31623316
  • 587 + 31622729 = 31623316

Showing the first eight; more decompositions exist.
