Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532526, here are decompositions:

5 + 31532521 = 31532526
19 + 31532507 = 31532526
29 + 31532497 = 31532526
37 + 31532489 = 31532526
89 + 31532437 = 31532526
97 + 31532429 = 31532526
173 + 31532353 = 31532526
197 + 31532329 = 31532526

Showing the first eight; more decompositions exist.
