Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463948, here are decompositions:

7 + 31463941 = 31463948
37 + 31463911 = 31463948
151 + 31463797 = 31463948
181 + 31463767 = 31463948
421 + 31463527 = 31463948
541 + 31463407 = 31463948
619 + 31463329 = 31463948
631 + 31463317 = 31463948

Showing the first eight; more decompositions exist.
