Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481470, here are decompositions:

11 + 31481459 = 31481470
17 + 31481453 = 31481470
101 + 31481369 = 31481470
149 + 31481321 = 31481470
233 + 31481237 = 31481470
239 + 31481231 = 31481470
263 + 31481207 = 31481470
269 + 31481201 = 31481470

Showing the first eight; more decompositions exist.
