Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560252, here are decompositions:

5 + 31560247 = 31560252
13 + 31560239 = 31560252
19 + 31560233 = 31560252
79 + 31560173 = 31560252
173 + 31560079 = 31560252
179 + 31560073 = 31560252
193 + 31560059 = 31560252
223 + 31560029 = 31560252

Showing the first eight; more decompositions exist.
