Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574044, here are decompositions:

3 + 31574041 = 31574044
23 + 31574021 = 31574044
83 + 31573961 = 31574044
113 + 31573931 = 31574044
191 + 31573853 = 31574044
197 + 31573847 = 31574044
251 + 31573793 = 31574044
347 + 31573697 = 31574044

Showing the first eight; more decompositions exist.
