Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560336, here are decompositions:

29 + 31560307 = 31560336
37 + 31560299 = 31560336
43 + 31560293 = 31560336
89 + 31560247 = 31560336
97 + 31560239 = 31560336
103 + 31560233 = 31560336
109 + 31560227 = 31560336
163 + 31560173 = 31560336

Showing the first eight; more decompositions exist.
