Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484308, here are decompositions:

5 + 31484303 = 31484308
41 + 31484267 = 31484308
71 + 31484237 = 31484308
101 + 31484207 = 31484308
131 + 31484177 = 31484308
179 + 31484129 = 31484308
227 + 31484081 = 31484308
239 + 31484069 = 31484308

Showing the first eight; more decompositions exist.
