Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494352, here are decompositions:

5 + 31494347 = 31494352
59 + 31494293 = 31494352
89 + 31494263 = 31494352
173 + 31494179 = 31494352
191 + 31494161 = 31494352
233 + 31494119 = 31494352
269 + 31494083 = 31494352
311 + 31494041 = 31494352

Showing the first eight; more decompositions exist.
