Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470168, here are decompositions:

  • 29 + 2147470139 = 2147470168
  • 101 + 2147470067 = 2147470168
  • 149 + 2147470019 = 2147470168
  • 251 + 2147469917 = 2147470168
  • 509 + 2147469659 = 2147470168
  • 647 + 2147469521 = 2147470168
  • 677 + 2147469491 = 2147470168
  • 719 + 2147469449 = 2147470168

Showing the first eight; more decompositions exist.
