Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466242, here are decompositions:

179 + 31466063 = 31466242
191 + 31466051 = 31466242
239 + 31466003 = 31466242
263 + 31465979 = 31466242
461 + 31465781 = 31466242
569 + 31465673 = 31466242
593 + 31465649 = 31466242
641 + 31465601 = 31466242

Showing the first eight; more decompositions exist.
