Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479450, here are decompositions:

11 + 31479439 = 31479450
29 + 31479421 = 31479450
31 + 31479419 = 31479450
113 + 31479337 = 31479450
151 + 31479299 = 31479450
173 + 31479277 = 31479450
179 + 31479271 = 31479450
181 + 31479269 = 31479450

Showing the first eight; more decompositions exist.
