Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564346, here are decompositions:

13 + 31564333 = 31564346
19 + 31564327 = 31564346
97 + 31564249 = 31564346
103 + 31564243 = 31564346
109 + 31564237 = 31564346
139 + 31564207 = 31564346
199 + 31564147 = 31564346
337 + 31564009 = 31564346

Showing the first eight; more decompositions exist.
