Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584536, here are decompositions:

  • 7 + 2147584529 = 2147584536
  • 17 + 2147584519 = 2147584536
  • 79 + 2147584457 = 2147584536
  • 193 + 2147584343 = 2147584536
  • 277 + 2147584259 = 2147584536
  • 283 + 2147584253 = 2147584536
  • 379 + 2147584157 = 2147584536
  • 467 + 2147584069 = 2147584536

Showing the first eight; more decompositions exist.
