Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497394, here are decompositions:

  • 73 + 2147497321 = 2147497394
  • 151 + 2147497243 = 2147497394
  • 157 + 2147497237 = 2147497394
  • 193 + 2147497201 = 2147497394
  • 313 + 2147497081 = 2147497394
  • 397 + 2147496997 = 2147497394
  • 433 + 2147496961 = 2147497394
  • 457 + 2147496937 = 2147497394

Showing the first eight; more decompositions exist.
