Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567564, here are decompositions:

5 + 31567559 = 31567564
11 + 31567553 = 31567564
53 + 31567511 = 31567564
113 + 31567451 = 31567564
137 + 31567427 = 31567564
167 + 31567397 = 31567564
251 + 31567313 = 31567564
293 + 31567271 = 31567564

Showing the first eight; more decompositions exist.
