Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488942, here are decompositions:

23 + 2147488919 = 2147488942
29 + 2147488913 = 2147488942
83 + 2147488859 = 2147488942
149 + 2147488793 = 2147488942
191 + 2147488751 = 2147488942
251 + 2147488691 = 2147488942
383 + 2147488559 = 2147488942
881 + 2147488061 = 2147488942

Showing the first eight; more decompositions exist.

IPv4 address
