Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486530, here are decompositions:

3 + 2147486527 = 2147486530
17 + 2147486513 = 2147486530
23 + 2147486507 = 2147486530
29 + 2147486501 = 2147486530
71 + 2147486459 = 2147486530
107 + 2147486423 = 2147486530
131 + 2147486399 = 2147486530
191 + 2147486339 = 2147486530

Showing the first eight; more decompositions exist.

IPv4 address
