Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564204, here are decompositions:

41 + 31564163 = 31564204
47 + 31564157 = 31564204
71 + 31564133 = 31564204
101 + 31564103 = 31564204
251 + 31563953 = 31564204
257 + 31563947 = 31564204
263 + 31563941 = 31564204
293 + 31563911 = 31564204

Showing the first eight; more decompositions exist.
