Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624348, here are decompositions:

  • 5 + 31624343 = 31624348
  • 11 + 31624337 = 31624348
  • 17 + 31624331 = 31624348
  • 71 + 31624277 = 31624348
  • 131 + 31624217 = 31624348
  • 347 + 31624001 = 31624348
  • 359 + 31623989 = 31624348
  • 389 + 31623959 = 31624348

Showing the first eight; more decompositions exist.
