Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487786, here are decompositions:

5 + 2147487781 = 2147487786
7 + 2147487779 = 2147487786
13 + 2147487773 = 2147487786
29 + 2147487757 = 2147487786
83 + 2147487703 = 2147487786
97 + 2147487689 = 2147487786
137 + 2147487649 = 2147487786
149 + 2147487637 = 2147487786

Showing the first eight; more decompositions exist.

IPv4 address
