Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499434, here are decompositions:

  • 43 + 2147499391 = 2147499434
  • 151 + 2147499283 = 2147499434
  • 181 + 2147499253 = 2147499434
  • 193 + 2147499241 = 2147499434
  • 397 + 2147499037 = 2147499434
  • 523 + 2147498911 = 2147499434
  • 541 + 2147498893 = 2147499434
  • 607 + 2147498827 = 2147499434

Showing the first eight; more decompositions exist.
