Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498286, here are decompositions:

  • 7 + 2147498279 = 2147498286
  • 97 + 2147498189 = 2147498286
  • 107 + 2147498179 = 2147498286
  • 139 + 2147498147 = 2147498286
  • 337 + 2147497949 = 2147498286
  • 347 + 2147497939 = 2147498286
  • 379 + 2147497907 = 2147498286
  • 397 + 2147497889 = 2147498286

Showing the first eight; more decompositions exist.
