Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487280, here are decompositions:

  • 11 + 2147487269 = 2147487280
  • 53 + 2147487227 = 2147487280
  • 167 + 2147487113 = 2147487280
  • 251 + 2147487029 = 2147487280
  • 311 + 2147486969 = 2147487280
  • 353 + 2147486927 = 2147487280
  • 401 + 2147486879 = 2147487280
  • 431 + 2147486849 = 2147487280

Showing the first eight; more decompositions exist.
