Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536618, here are decompositions:

5 + 31536613 = 31536618
11 + 31536607 = 31536618
67 + 31536551 = 31536618
79 + 31536539 = 31536618
89 + 31536529 = 31536618
97 + 31536521 = 31536618
137 + 31536481 = 31536618
227 + 31536391 = 31536618

Showing the first eight; more decompositions exist.
