Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574034, here are decompositions:

13 + 31574021 = 31574034
67 + 31573967 = 31574034
73 + 31573961 = 31574034
103 + 31573931 = 31574034
181 + 31573853 = 31574034
211 + 31573823 = 31574034
241 + 31573793 = 31574034
277 + 31573757 = 31574034

Showing the first eight; more decompositions exist.
