Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497274, here are decompositions:

  • 31 + 2147497243 = 2147497274
  • 37 + 2147497237 = 2147497274
  • 73 + 2147497201 = 2147497274
  • 193 + 2147497081 = 2147497274
  • 277 + 2147496997 = 2147497274
  • 313 + 2147496961 = 2147497274
  • 337 + 2147496937 = 2147497274
  • 421 + 2147496853 = 2147497274

Showing the first eight; more decompositions exist.
