Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569522, here are decompositions:

31 + 31569491 = 31569522
41 + 31569481 = 31569522
43 + 31569479 = 31569522
73 + 31569449 = 31569522
163 + 31569359 = 31569522
241 + 31569281 = 31569522
263 + 31569259 = 31569522
293 + 31569229 = 31569522

Showing the first eight; more decompositions exist.
