Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612252, here are decompositions:

11 + 31612241 = 31612252
29 + 31612223 = 31612252
53 + 31612199 = 31612252
101 + 31612151 = 31612252
131 + 31612121 = 31612252
173 + 31612079 = 31612252
239 + 31612013 = 31612252
311 + 31611941 = 31612252

Showing the first eight; more decompositions exist.
