Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502958, here are decompositions:

5 + 31502953 = 31502958
17 + 31502941 = 31502958
31 + 31502927 = 31502958
61 + 31502897 = 31502958
101 + 31502857 = 31502958
181 + 31502777 = 31502958
197 + 31502761 = 31502958
257 + 31502701 = 31502958

Showing the first eight; more decompositions exist.
