Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624376, here are decompositions:

  • 13 + 31624363 = 31624376
  • 19 + 31624357 = 31624376
  • 37 + 31624339 = 31624376
  • 229 + 31624147 = 31624376
  • 307 + 31624069 = 31624376
  • 373 + 31624003 = 31624376
  • 397 + 31623979 = 31624376
  • 409 + 31623967 = 31624376

Showing the first eight; more decompositions exist.
