Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497914, here are decompositions:

31 + 31497883 = 31497914
43 + 31497871 = 31497914
157 + 31497757 = 31497914
163 + 31497751 = 31497914
193 + 31497721 = 31497914
241 + 31497673 = 31497914
277 + 31497637 = 31497914
313 + 31497601 = 31497914

Showing the first eight; more decompositions exist.
