Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534450, here are decompositions:

23 + 31534427 = 31534450
107 + 31534343 = 31534450
149 + 31534301 = 31534450
179 + 31534271 = 31534450
251 + 31534199 = 31534450
263 + 31534187 = 31534450
281 + 31534169 = 31534450
347 + 31534103 = 31534450

Showing the first eight; more decompositions exist.
