Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484356, here are decompositions:

3 + 31484353 = 31484356
17 + 31484339 = 31484356
53 + 31484303 = 31484356
89 + 31484267 = 31484356
149 + 31484207 = 31484356
179 + 31484177 = 31484356
227 + 31484129 = 31484356
263 + 31484093 = 31484356

Showing the first eight; more decompositions exist.
