Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487884, here are decompositions:

13 + 2147487871 = 2147487884
67 + 2147487817 = 2147487884
103 + 2147487781 = 2147487884
127 + 2147487757 = 2147487884
181 + 2147487703 = 2147487884
193 + 2147487691 = 2147487884
277 + 2147487607 = 2147487884
313 + 2147487571 = 2147487884

Showing the first eight; more decompositions exist.

IPv4 address
