Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548426, here are decompositions:

83 + 31548343 = 31548426
103 + 31548323 = 31548426
113 + 31548313 = 31548426
127 + 31548299 = 31548426
139 + 31548287 = 31548426
157 + 31548269 = 31548426
163 + 31548263 = 31548426
277 + 31548149 = 31548426

Showing the first eight; more decompositions exist.
