Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492948, here are decompositions:

5 + 31492943 = 31492948
41 + 31492907 = 31492948
89 + 31492859 = 31492948
101 + 31492847 = 31492948
107 + 31492841 = 31492948
167 + 31492781 = 31492948
191 + 31492757 = 31492948
197 + 31492751 = 31492948

Showing the first eight; more decompositions exist.
