Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491308, here are decompositions:

31 + 2147491277 = 2147491308
47 + 2147491261 = 2147491308
59 + 2147491249 = 2147491308
71 + 2147491237 = 2147491308
89 + 2147491219 = 2147491308
107 + 2147491201 = 2147491308
181 + 2147491127 = 2147491308
197 + 2147491111 = 2147491308

Showing the first eight; more decompositions exist.

IPv4 address
