Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460586, here are decompositions:

5 + 31460581 = 31460586
37 + 31460549 = 31460586
89 + 31460497 = 31460586
103 + 31460483 = 31460586
173 + 31460413 = 31460586
239 + 31460347 = 31460586
257 + 31460329 = 31460586
293 + 31460293 = 31460586

Showing the first eight; more decompositions exist.
