Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467470, here are decompositions:

  • 7 + 2147467463 = 2147467470
  • 67 + 2147467403 = 2147467470
  • 103 + 2147467367 = 2147467470
  • 131 + 2147467339 = 2147467470
  • 139 + 2147467331 = 2147467470
  • 149 + 2147467321 = 2147467470
  • 251 + 2147467219 = 2147467470
  • 307 + 2147467163 = 2147467470

Showing the first eight; more decompositions exist.
