Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566952, here are decompositions:

41 + 31566911 = 31566952
89 + 31566863 = 31566952
113 + 31566839 = 31566952
149 + 31566803 = 31566952
239 + 31566713 = 31566952
293 + 31566659 = 31566952
353 + 31566599 = 31566952
479 + 31566473 = 31566952

Showing the first eight; more decompositions exist.
