Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500494, here are decompositions:

  • 151 + 2147500343 = 2147500494
  • 193 + 2147500301 = 2147500494
  • 197 + 2147500297 = 2147500494
  • 311 + 2147500183 = 2147500494
  • 317 + 2147500177 = 2147500494
  • 367 + 2147500127 = 2147500494
  • 383 + 2147500111 = 2147500494
  • 401 + 2147500093 = 2147500494

Showing the first eight; more decompositions exist.
