Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564454, here are decompositions:

7 + 31564447 = 31564454
67 + 31564387 = 31564454
127 + 31564327 = 31564454
193 + 31564261 = 31564454
211 + 31564243 = 31564454
283 + 31564171 = 31564454
307 + 31564147 = 31564454
487 + 31563967 = 31564454

Showing the first eight; more decompositions exist.
