Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487242, here are decompositions:

73 + 2147487169 = 2147487242
193 + 2147487049 = 2147487242
601 + 2147486641 = 2147487242
643 + 2147486599 = 2147487242
811 + 2147486431 = 2147487242
829 + 2147486413 = 2147487242
1039 + 2147486203 = 2147487242
1303 + 2147485939 = 2147487242

Showing the first eight; more decompositions exist.

IPv4 address
