Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147587974, here are decompositions:

  • 5 + 2147587969 = 2147587974
  • 11 + 2147587963 = 2147587974
  • 17 + 2147587957 = 2147587974
  • 31 + 2147587943 = 2147587974
  • 41 + 2147587933 = 2147587974
  • 251 + 2147587723 = 2147587974
  • 271 + 2147587703 = 2147587974
  • 347 + 2147587627 = 2147587974

Showing the first eight; more decompositions exist.
