Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527948, here are decompositions:

7 + 31527941 = 31527948
17 + 31527931 = 31527948
61 + 31527887 = 31527948
131 + 31527817 = 31527948
167 + 31527781 = 31527948
239 + 31527709 = 31527948
251 + 31527697 = 31527948
271 + 31527677 = 31527948

Showing the first eight; more decompositions exist.
