Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564694, here are decompositions:

37 + 31564657 = 31564694
103 + 31564591 = 31564694
163 + 31564531 = 31564694
193 + 31564501 = 31564694
307 + 31564387 = 31564694
367 + 31564327 = 31564694
373 + 31564321 = 31564694
433 + 31564261 = 31564694

Showing the first eight; more decompositions exist.
