Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485476, here are decompositions:

3 + 31485473 = 31485476
79 + 31485397 = 31485476
97 + 31485379 = 31485476
157 + 31485319 = 31485476
163 + 31485313 = 31485476
193 + 31485283 = 31485476
199 + 31485277 = 31485476
229 + 31485247 = 31485476

Showing the first eight; more decompositions exist.
