Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147587004, here are decompositions:

  • 127 + 2147586877 = 2147587004
  • 181 + 2147586823 = 2147587004
  • 193 + 2147586811 = 2147587004
  • 271 + 2147586733 = 2147587004
  • 337 + 2147586667 = 2147587004
  • 457 + 2147586547 = 2147587004
  • 547 + 2147586457 = 2147587004
  • 643 + 2147586361 = 2147587004

Showing the first eight; more decompositions exist.
