Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485252, here are decompositions:

5 + 31485247 = 31485252
31 + 31485221 = 31485252
59 + 31485193 = 31485252
61 + 31485191 = 31485252
131 + 31485121 = 31485252
151 + 31485101 = 31485252
173 + 31485079 = 31485252
193 + 31485059 = 31485252

Showing the first eight; more decompositions exist.
