Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580352, here are decompositions:

  • 5 + 31580347 = 31580352
  • 29 + 31580323 = 31580352
  • 31 + 31580321 = 31580352
  • 59 + 31580293 = 31580352
  • 73 + 31580279 = 31580352
  • 79 + 31580273 = 31580352
  • 113 + 31580239 = 31580352
  • 131 + 31580221 = 31580352

Showing the first eight; more decompositions exist.
