Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484266, here are decompositions:

29 + 31484237 = 31484266
59 + 31484207 = 31484266
89 + 31484177 = 31484266
137 + 31484129 = 31484266
173 + 31484093 = 31484266
197 + 31484069 = 31484266
347 + 31483919 = 31484266
353 + 31483913 = 31484266

Showing the first eight; more decompositions exist.
