Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460968, here are decompositions:

17 + 31460951 = 31460968
41 + 31460927 = 31460968
89 + 31460879 = 31460968
131 + 31460837 = 31460968
137 + 31460831 = 31460968
239 + 31460729 = 31460968
251 + 31460717 = 31460968
311 + 31460657 = 31460968

Showing the first eight; more decompositions exist.
