Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484416, here are decompositions:

3 + 31484413 = 31484416
53 + 31484363 = 31484416
113 + 31484303 = 31484416
149 + 31484267 = 31484416
179 + 31484237 = 31484416
239 + 31484177 = 31484416
347 + 31484069 = 31484416
503 + 31483913 = 31484416

Showing the first eight; more decompositions exist.
