Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574076, here are decompositions:

5 + 31574071 = 31574076
29 + 31574047 = 31574076
109 + 31573967 = 31574076
223 + 31573853 = 31574076
229 + 31573847 = 31574076
257 + 31573819 = 31574076
283 + 31573793 = 31574076
379 + 31573697 = 31574076

Showing the first eight; more decompositions exist.
