Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564604, here are decompositions:

13 + 31564591 = 31564604
73 + 31564531 = 31564604
103 + 31564501 = 31564604
157 + 31564447 = 31564604
271 + 31564333 = 31564604
277 + 31564327 = 31564604
283 + 31564321 = 31564604
367 + 31564237 = 31564604

Showing the first eight; more decompositions exist.
