Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657146, here are decompositions:

23 + 8657123 = 8657146
137 + 8657009 = 8657146
167 + 8656979 = 8657146
227 + 8656919 = 8657146
317 + 8656829 = 8657146
359 + 8656787 = 8657146
419 + 8656727 = 8657146
479 + 8656667 = 8657146

Showing the first eight; more decompositions exist.
