Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532652, here are decompositions:

13 + 31532639 = 31532652
59 + 31532593 = 31532652
71 + 31532581 = 31532652
79 + 31532573 = 31532652
101 + 31532551 = 31532652
113 + 31532539 = 31532652
131 + 31532521 = 31532652
163 + 31532489 = 31532652

Showing the first eight; more decompositions exist.
