Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657446, here are decompositions:

23 + 8657423 = 8657446
59 + 8657387 = 8657446
89 + 8657357 = 8657446
113 + 8657333 = 8657446
137 + 8657309 = 8657446
197 + 8657249 = 8657446
467 + 8656979 = 8657446
599 + 8656847 = 8657446

Showing the first eight; more decompositions exist.
