Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574022, here are decompositions:

23 + 31573999 = 31574022
61 + 31573961 = 31574022
163 + 31573859 = 31574022
191 + 31573831 = 31574022
199 + 31573823 = 31574022
229 + 31573793 = 31574022
269 + 31573753 = 31574022
379 + 31573643 = 31574022

Showing the first eight; more decompositions exist.
