Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564266, here are decompositions:

5 + 31564261 = 31564266
17 + 31564249 = 31564266
23 + 31564243 = 31564266
29 + 31564237 = 31564266
37 + 31564229 = 31564266
59 + 31564207 = 31564266
103 + 31564163 = 31564266
109 + 31564157 = 31564266

Showing the first eight; more decompositions exist.
