Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487834, here are decompositions:

5 + 2147487829 = 2147487834
7 + 2147487827 = 2147487834
17 + 2147487817 = 2147487834
31 + 2147487803 = 2147487834
53 + 2147487781 = 2147487834
61 + 2147487773 = 2147487834
83 + 2147487751 = 2147487834
131 + 2147487703 = 2147487834

Showing the first eight; more decompositions exist.

IPv4 address
