Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560244, here are decompositions:

5 + 31560239 = 31560244
11 + 31560233 = 31560244
17 + 31560227 = 31560244
71 + 31560173 = 31560244
137 + 31560107 = 31560244
197 + 31560047 = 31560244
263 + 31559981 = 31560244
293 + 31559951 = 31560244

Showing the first eight; more decompositions exist.
