Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460298, here are decompositions:

5 + 31460293 = 31460298
7 + 31460291 = 31460298
17 + 31460281 = 31460298
19 + 31460279 = 31460298
31 + 31460267 = 31460298
101 + 31460197 = 31460298
131 + 31460167 = 31460298
281 + 31460017 = 31460298

Showing the first eight; more decompositions exist.
