Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147587830, here are decompositions:

  • 41 + 2147587789 = 2147587830
  • 107 + 2147587723 = 2147587830
  • 127 + 2147587703 = 2147587830
  • 211 + 2147587619 = 2147587830
  • 233 + 2147587597 = 2147587830
  • 307 + 2147587523 = 2147587830
  • 313 + 2147587517 = 2147587830
  • 317 + 2147587513 = 2147587830

Showing the first eight; more decompositions exist.
