Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532646, here are decompositions:

7 + 31532639 = 31532646
53 + 31532593 = 31532646
59 + 31532587 = 31532646
73 + 31532573 = 31532646
107 + 31532539 = 31532646
139 + 31532507 = 31532646
149 + 31532497 = 31532646
157 + 31532489 = 31532646

Showing the first eight; more decompositions exist.
