Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532502, here are decompositions:

5 + 31532497 = 31532502
13 + 31532489 = 31532502
73 + 31532429 = 31532502
101 + 31532401 = 31532502
149 + 31532353 = 31532502
163 + 31532339 = 31532502
173 + 31532329 = 31532502
179 + 31532323 = 31532502

Showing the first eight; more decompositions exist.
