Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488574, here are decompositions:

  • 31 + 2147488543 = 2147488574
  • 157 + 2147488417 = 2147488574
  • 163 + 2147488411 = 2147488574
  • 193 + 2147488381 = 2147488574
  • 241 + 2147488333 = 2147488574
  • 421 + 2147488153 = 2147488574
  • 463 + 2147488111 = 2147488574
  • 547 + 2147488027 = 2147488574

Showing the first eight; more decompositions exist.
