Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491608, here are decompositions:

5 + 2147491603 = 2147491608
11 + 2147491597 = 2147491608
61 + 2147491547 = 2147491608
71 + 2147491537 = 2147491608
131 + 2147491477 = 2147491608
191 + 2147491417 = 2147491608
239 + 2147491369 = 2147491608
331 + 2147491277 = 2147491608

Showing the first eight; more decompositions exist.

IPv4 address
