Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574108, here are decompositions:

37 + 31574071 = 31574108
61 + 31574047 = 31574108
67 + 31574041 = 31574108
109 + 31573999 = 31574108
151 + 31573957 = 31574108
277 + 31573831 = 31574108
487 + 31573621 = 31574108
547 + 31573561 = 31574108

Showing the first eight; more decompositions exist.
