Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536422, here are decompositions:

19 + 31536403 = 31536422
31 + 31536391 = 31536422
61 + 31536361 = 31536422
109 + 31536313 = 31536422
199 + 31536223 = 31536422
373 + 31536049 = 31536422
439 + 31535983 = 31536422
601 + 31535821 = 31536422

Showing the first eight; more decompositions exist.
