Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464948, here are decompositions:

7 + 31464941 = 31464948
127 + 31464821 = 31464948
139 + 31464809 = 31464948
167 + 31464781 = 31464948
191 + 31464757 = 31464948
239 + 31464709 = 31464948
331 + 31464617 = 31464948
367 + 31464581 = 31464948

Showing the first eight; more decompositions exist.
