Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494402, here are decompositions:

13 + 31494389 = 31494402
101 + 31494301 = 31494402
109 + 31494293 = 31494402
139 + 31494263 = 31494402
223 + 31494179 = 31494402
241 + 31494161 = 31494402
283 + 31494119 = 31494402
311 + 31494091 = 31494402

Showing the first eight; more decompositions exist.
