Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494298, here are decompositions:

5 + 31494293 = 31494298
41 + 31494257 = 31494298
137 + 31494161 = 31494298
179 + 31494119 = 31494298
257 + 31494041 = 31494298
347 + 31493951 = 31494298
389 + 31493909 = 31494298
509 + 31493789 = 31494298

Showing the first eight; more decompositions exist.
