Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532658, here are decompositions:

5 + 31532653 = 31532658
19 + 31532639 = 31532658
61 + 31532597 = 31532658
71 + 31532587 = 31532658
107 + 31532551 = 31532658
137 + 31532521 = 31532658
151 + 31532507 = 31532658
181 + 31532477 = 31532658

Showing the first eight; more decompositions exist.
