Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498310, here are decompositions:

3 + 31498307 = 31498310
31 + 31498279 = 31498310
37 + 31498273 = 31498310
97 + 31498213 = 31498310
199 + 31498111 = 31498310
223 + 31498087 = 31498310
241 + 31498069 = 31498310
271 + 31498039 = 31498310

Showing the first eight; more decompositions exist.
