Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484326, here are decompositions:

23 + 31484303 = 31484326
59 + 31484267 = 31484326
89 + 31484237 = 31484326
149 + 31484177 = 31484326
197 + 31484129 = 31484326
233 + 31484093 = 31484326
257 + 31484069 = 31484326
347 + 31483979 = 31484326

Showing the first eight; more decompositions exist.
