Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564522, here are decompositions:

5 + 31564517 = 31564522
83 + 31564439 = 31564522
89 + 31564433 = 31564522
131 + 31564391 = 31564522
191 + 31564331 = 31564522
251 + 31564271 = 31564522
281 + 31564241 = 31564522
293 + 31564229 = 31564522

Showing the first eight; more decompositions exist.
