Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574066, here are decompositions:

19 + 31574047 = 31574066
67 + 31573999 = 31574066
109 + 31573957 = 31574066
313 + 31573753 = 31574066
439 + 31573627 = 31574066
673 + 31573393 = 31574066
709 + 31573357 = 31574066
787 + 31573279 = 31574066

Showing the first eight; more decompositions exist.
