Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491318, here are decompositions:

  • 41 + 2147491277 = 2147491318
  • 101 + 2147491217 = 2147491318
  • 179 + 2147491139 = 2147491318
  • 191 + 2147491127 = 2147491318
  • 227 + 2147491091 = 2147491318
  • 251 + 2147491067 = 2147491318
  • 257 + 2147491061 = 2147491318
  • 281 + 2147491037 = 2147491318

Showing the first eight; more decompositions exist.
