Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536410, here are decompositions:

7 + 31536403 = 31536410
13 + 31536397 = 31536410
19 + 31536391 = 31536410
97 + 31536313 = 31536410
223 + 31536187 = 31536410
313 + 31536097 = 31536410
349 + 31536061 = 31536410
463 + 31535947 = 31536410

Showing the first eight; more decompositions exist.
