Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564296, here are decompositions:

47 + 31564249 = 31564296
53 + 31564243 = 31564296
59 + 31564237 = 31564296
67 + 31564229 = 31564296
89 + 31564207 = 31564296
139 + 31564157 = 31564296
149 + 31564147 = 31564296
157 + 31564139 = 31564296

Showing the first eight; more decompositions exist.
