Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564414, here are decompositions:

23 + 31564391 = 31564414
53 + 31564361 = 31564414
83 + 31564331 = 31564414
173 + 31564241 = 31564414
251 + 31564163 = 31564414
257 + 31564157 = 31564414
281 + 31564133 = 31564414
311 + 31564103 = 31564414

Showing the first eight; more decompositions exist.
