Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564634, here are decompositions:

43 + 31564591 = 31564634
103 + 31564531 = 31564634
307 + 31564327 = 31564634
313 + 31564321 = 31564634
373 + 31564261 = 31564634
397 + 31564237 = 31564634
463 + 31564171 = 31564634
487 + 31564147 = 31564634

Showing the first eight; more decompositions exist.
