Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529562, here are decompositions:

5 + 31529557 = 31529562
11 + 31529551 = 31529562
23 + 31529539 = 31529562
41 + 31529521 = 31529562
83 + 31529479 = 31529562
131 + 31529431 = 31529562
149 + 31529413 = 31529562
241 + 31529321 = 31529562

Showing the first eight; more decompositions exist.
