Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560364, here are decompositions:

23 + 31560341 = 31560364
71 + 31560293 = 31560364
113 + 31560251 = 31560364
131 + 31560233 = 31560364
137 + 31560227 = 31560364
191 + 31560173 = 31560364
257 + 31560107 = 31560364
317 + 31560047 = 31560364

Showing the first eight; more decompositions exist.
