Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584672, here are decompositions:

  • 3 + 2147584669 = 2147584672
  • 11 + 2147584661 = 2147584672
  • 281 + 2147584391 = 2147584672
  • 419 + 2147584253 = 2147584672
  • 491 + 2147584181 = 2147584672
  • 659 + 2147584013 = 2147584672
  • 683 + 2147583989 = 2147584672
  • 809 + 2147583863 = 2147584672

Showing the first eight; more decompositions exist.
