Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484516, here are decompositions:

3 + 31484513 = 31484516
13 + 31484503 = 31484516
67 + 31484449 = 31484516
103 + 31484413 = 31484516
139 + 31484377 = 31484516
157 + 31484359 = 31484516
163 + 31484353 = 31484516
199 + 31484317 = 31484516

Showing the first eight; more decompositions exist.
