Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564496, here are decompositions:

37 + 31564459 = 31564496
109 + 31564387 = 31564496
163 + 31564333 = 31564496
349 + 31564147 = 31564496
367 + 31564129 = 31564496
487 + 31564009 = 31564496
547 + 31563949 = 31564496
619 + 31563877 = 31564496

Showing the first eight; more decompositions exist.
