Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534498, here are decompositions:

5 + 31534493 = 31534498
11 + 31534487 = 31534498
41 + 31534457 = 31534498
71 + 31534427 = 31534498
197 + 31534301 = 31534498
227 + 31534271 = 31534498
251 + 31534247 = 31534498
257 + 31534241 = 31534498

Showing the first eight; more decompositions exist.
