Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468646, here are decompositions:

73 + 31468573 = 31468646
103 + 31468543 = 31468646
193 + 31468453 = 31468646
199 + 31468447 = 31468646
277 + 31468369 = 31468646
487 + 31468159 = 31468646
499 + 31468147 = 31468646
619 + 31468027 = 31468646

Showing the first eight; more decompositions exist.
