Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546564, here are decompositions:

11 + 31546553 = 31546564
107 + 31546457 = 31546564
113 + 31546451 = 31546564
227 + 31546337 = 31546564
263 + 31546301 = 31546564
281 + 31546283 = 31546564
347 + 31546217 = 31546564
383 + 31546181 = 31546564

Showing the first eight; more decompositions exist.
