Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657278, here are decompositions:

29 + 8657249 = 8657278
41 + 8657237 = 8657278
167 + 8657111 = 8657278
257 + 8657021 = 8657278
269 + 8657009 = 8657278
359 + 8656919 = 8657278
431 + 8656847 = 8657278
449 + 8656829 = 8657278

Showing the first eight; more decompositions exist.
