Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460508, here are decompositions:

11 + 31460497 = 31460508
17 + 31460491 = 31460508
67 + 31460441 = 31460508
109 + 31460399 = 31460508
139 + 31460369 = 31460508
179 + 31460329 = 31460508
227 + 31460281 = 31460508
229 + 31460279 = 31460508

Showing the first eight; more decompositions exist.
