Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499560, here are decompositions:

  • 13 + 2147499547 = 2147499560
  • 79 + 2147499481 = 2147499560
  • 103 + 2147499457 = 2147499560
  • 109 + 2147499451 = 2147499560
  • 127 + 2147499433 = 2147499560
  • 181 + 2147499379 = 2147499560
  • 211 + 2147499349 = 2147499560
  • 277 + 2147499283 = 2147499560

Showing the first eight; more decompositions exist.
