Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532586, here are decompositions:

5 + 31532581 = 31532586
13 + 31532573 = 31532586
47 + 31532539 = 31532586
79 + 31532507 = 31532586
89 + 31532497 = 31532586
97 + 31532489 = 31532586
109 + 31532477 = 31532586
149 + 31532437 = 31532586

Showing the first eight; more decompositions exist.
