Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450792, here are decompositions:

3 + 31450789 = 31450792
5 + 31450787 = 31450792
11 + 31450781 = 31450792
29 + 31450763 = 31450792
53 + 31450739 = 31450792
71 + 31450721 = 31450792
173 + 31450619 = 31450792
179 + 31450613 = 31450792

Showing the first eight; more decompositions exist.
