Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516332, here are decompositions:

5 + 31516327 = 31516332
13 + 31516319 = 31516332
79 + 31516253 = 31516332
131 + 31516201 = 31516332
149 + 31516183 = 31516332
173 + 31516159 = 31516332
179 + 31516153 = 31516332
193 + 31516139 = 31516332

Showing the first eight; more decompositions exist.
