Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487904, here are decompositions:

  • 5 + 2147487899 = 2147487904
  • 71 + 2147487833 = 2147487904
  • 101 + 2147487803 = 2147487904
  • 131 + 2147487773 = 2147487904
  • 281 + 2147487623 = 2147487904
  • 293 + 2147487611 = 2147487904
  • 431 + 2147487473 = 2147487904
  • 503 + 2147487401 = 2147487904

Showing the first eight; more decompositions exist.
