Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484316, here are decompositions:

13 + 31484303 = 31484316
79 + 31484237 = 31484316
107 + 31484209 = 31484316
109 + 31484207 = 31484316
113 + 31484203 = 31484316
137 + 31484179 = 31484316
139 + 31484177 = 31484316
173 + 31484143 = 31484316

Showing the first eight; more decompositions exist.
