Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476924, here are decompositions:

7 + 31476917 = 31476924
43 + 31476881 = 31476924
53 + 31476871 = 31476924
71 + 31476853 = 31476924
103 + 31476821 = 31476924
181 + 31476743 = 31476924
191 + 31476733 = 31476924
197 + 31476727 = 31476924

Showing the first eight; more decompositions exist.
