Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460928, here are decompositions:

11 + 31460917 = 31460928
89 + 31460839 = 31460928
97 + 31460831 = 31460928
137 + 31460791 = 31460928
199 + 31460729 = 31460928
211 + 31460717 = 31460928
227 + 31460701 = 31460928
251 + 31460677 = 31460928

Showing the first eight; more decompositions exist.
