Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536146, here are decompositions:

97 + 31536049 = 31536146
127 + 31536019 = 31536146
163 + 31535983 = 31536146
199 + 31535947 = 31536146
337 + 31535809 = 31536146
349 + 31535797 = 31536146
643 + 31535503 = 31536146
727 + 31535419 = 31536146

Showing the first eight; more decompositions exist.
