Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560088, here are decompositions:

29 + 31560059 = 31560088
41 + 31560047 = 31560088
59 + 31560029 = 31560088
107 + 31559981 = 31560088
137 + 31559951 = 31560088
227 + 31559861 = 31560088
239 + 31559849 = 31560088
257 + 31559831 = 31560088

Showing the first eight; more decompositions exist.
