Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564364, here are decompositions:

3 + 31564361 = 31564364
31 + 31564333 = 31564364
37 + 31564327 = 31564364
43 + 31564321 = 31564364
103 + 31564261 = 31564364
127 + 31564237 = 31564364
157 + 31564207 = 31564364
193 + 31564171 = 31564364

Showing the first eight; more decompositions exist.
