Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482646, here are decompositions:

3 + 31482643 = 31482646
5 + 31482641 = 31482646
29 + 31482617 = 31482646
47 + 31482599 = 31482646
59 + 31482587 = 31482646
137 + 31482509 = 31482646
257 + 31482389 = 31482646
353 + 31482293 = 31482646

Showing the first eight; more decompositions exist.
