Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536494, here are decompositions:

13 + 31536481 = 31536494
97 + 31536397 = 31536494
103 + 31536391 = 31536494
181 + 31536313 = 31536494
271 + 31536223 = 31536494
307 + 31536187 = 31536494
397 + 31536097 = 31536494
433 + 31536061 = 31536494

Showing the first eight; more decompositions exist.
