Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584690, here are decompositions:

  • 11 + 2147584679 = 2147584690
  • 29 + 2147584661 = 2147584690
  • 137 + 2147584553 = 2147584690
  • 233 + 2147584457 = 2147584690
  • 347 + 2147584343 = 2147584690
  • 431 + 2147584259 = 2147584690
  • 509 + 2147584181 = 2147584690
  • 677 + 2147584013 = 2147584690

Showing the first eight; more decompositions exist.
