Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560052, here are decompositions:

5 + 31560047 = 31560052
23 + 31560029 = 31560052
71 + 31559981 = 31560052
101 + 31559951 = 31560052
191 + 31559861 = 31560052
239 + 31559813 = 31560052
269 + 31559783 = 31560052
281 + 31559771 = 31560052

Showing the first eight; more decompositions exist.
