Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548436, here are decompositions:

5 + 31548431 = 31548436
113 + 31548323 = 31548436
137 + 31548299 = 31548436
149 + 31548287 = 31548436
167 + 31548269 = 31548436
173 + 31548263 = 31548436
389 + 31548047 = 31548436
419 + 31548017 = 31548436

Showing the first eight; more decompositions exist.
