Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147583920, here are decompositions:

  • 127 + 2147583793 = 2147583920
  • 199 + 2147583721 = 2147583920
  • 211 + 2147583709 = 2147583920
  • 241 + 2147583679 = 2147583920
  • 367 + 2147583553 = 2147583920
  • 409 + 2147583511 = 2147583920
  • 439 + 2147583481 = 2147583920
  • 523 + 2147583397 = 2147583920

Showing the first eight; more decompositions exist.
