Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624336, here are decompositions:

  • 5 + 31624331 = 31624336
  • 53 + 31624283 = 31624336
  • 59 + 31624277 = 31624336
  • 347 + 31623989 = 31624336
  • 353 + 31623983 = 31624336
  • 383 + 31623953 = 31624336
  • 389 + 31623947 = 31624336
  • 449 + 31623887 = 31624336

Showing the first eight; more decompositions exist.
