Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564294, here are decompositions:

23 + 31564271 = 31564294
53 + 31564241 = 31564294
131 + 31564163 = 31564294
137 + 31564157 = 31564294
191 + 31564103 = 31564294
347 + 31563947 = 31564294
353 + 31563941 = 31564294
383 + 31563911 = 31564294

Showing the first eight; more decompositions exist.
