Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529652, here are decompositions:

23 + 31529629 = 31529652
29 + 31529623 = 31529652
59 + 31529593 = 31529652
101 + 31529551 = 31529652
113 + 31529539 = 31529652
131 + 31529521 = 31529652
173 + 31529479 = 31529652
181 + 31529471 = 31529652

Showing the first eight; more decompositions exist.
