Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500490, here are decompositions:

  • 139 + 2147500351 = 2147500490
  • 151 + 2147500339 = 2147500490
  • 193 + 2147500297 = 2147500490
  • 307 + 2147500183 = 2147500490
  • 313 + 2147500177 = 2147500490
  • 367 + 2147500123 = 2147500490
  • 379 + 2147500111 = 2147500490
  • 397 + 2147500093 = 2147500490

Showing the first eight; more decompositions exist.
