Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147587776, here are decompositions:

  • 53 + 2147587723 = 2147587776
  • 73 + 2147587703 = 2147587776
  • 149 + 2147587627 = 2147587776
  • 157 + 2147587619 = 2147587776
  • 167 + 2147587609 = 2147587776
  • 179 + 2147587597 = 2147587776
  • 193 + 2147587583 = 2147587776
  • 263 + 2147587513 = 2147587776

Showing the first eight; more decompositions exist.
