Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470386, here are decompositions:

  • 53 + 2147470333 = 2147470386
  • 59 + 2147470327 = 2147470386
  • 73 + 2147470313 = 2147470386
  • 137 + 2147470249 = 2147470386
  • 157 + 2147470229 = 2147470386
  • 239 + 2147470147 = 2147470386
  • 263 + 2147470123 = 2147470386
  • 359 + 2147470027 = 2147470386

Showing the first eight; more decompositions exist.
