Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482266, here are decompositions:

19 + 31482247 = 31482266
37 + 31482229 = 31482266
97 + 31482169 = 31482266
163 + 31482103 = 31482266
199 + 31482067 = 31482266
223 + 31482043 = 31482266
229 + 31482037 = 31482266
367 + 31481899 = 31482266

Showing the first eight; more decompositions exist.
