Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532538, here are decompositions:

17 + 31532521 = 31532538
31 + 31532507 = 31532538
41 + 31532497 = 31532538
61 + 31532477 = 31532538
101 + 31532437 = 31532538
109 + 31532429 = 31532538
137 + 31532401 = 31532538
197 + 31532341 = 31532538

Showing the first eight; more decompositions exist.
