Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536660, here are decompositions:

31 + 31536629 = 31536660
47 + 31536613 = 31536660
53 + 31536607 = 31536660
109 + 31536551 = 31536660
131 + 31536529 = 31536660
139 + 31536521 = 31536660
179 + 31536481 = 31536660
257 + 31536403 = 31536660

Showing the first eight; more decompositions exist.
