Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485940, here are decompositions:

13 + 2147485927 = 2147485940
43 + 2147485897 = 2147485940
73 + 2147485867 = 2147485940
79 + 2147485861 = 2147485940
97 + 2147485843 = 2147485940
181 + 2147485759 = 2147485940
349 + 2147485591 = 2147485940
367 + 2147485573 = 2147485940

Showing the first eight; more decompositions exist.

IPv4 address
