Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494268, here are decompositions:

5 + 31494263 = 31494268
11 + 31494257 = 31494268
89 + 31494179 = 31494268
107 + 31494161 = 31494268
149 + 31494119 = 31494268
227 + 31494041 = 31494268
269 + 31493999 = 31494268
317 + 31493951 = 31494268

Showing the first eight; more decompositions exist.
