Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564594, here are decompositions:

3 + 31564591 = 31564594
233 + 31564361 = 31564594
263 + 31564331 = 31564594
353 + 31564241 = 31564594
431 + 31564163 = 31564594
461 + 31564133 = 31564594
491 + 31564103 = 31564594
641 + 31563953 = 31564594

Showing the first eight; more decompositions exist.
