Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500398, here are decompositions:

  • 37 + 2147500361 = 2147500398
  • 47 + 2147500351 = 2147500398
  • 59 + 2147500339 = 2147500398
  • 97 + 2147500301 = 2147500398
  • 101 + 2147500297 = 2147500398
  • 139 + 2147500259 = 2147500398
  • 151 + 2147500247 = 2147500398
  • 157 + 2147500241 = 2147500398

Showing the first eight; more decompositions exist.
