Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492600, here are decompositions:

3 + 31492597 = 31492600
23 + 31492577 = 31492600
47 + 31492553 = 31492600
59 + 31492541 = 31492600
71 + 31492529 = 31492600
107 + 31492493 = 31492600
179 + 31492421 = 31492600
197 + 31492403 = 31492600

Showing the first eight; more decompositions exist.
