Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657498, here are decompositions:

37 + 8657461 = 8657498
67 + 8657431 = 8657498
277 + 8657221 = 8657498
337 + 8657161 = 8657498
457 + 8657041 = 8657498
601 + 8656897 = 8657498
607 + 8656891 = 8657498
691 + 8656807 = 8657498

Showing the first eight; more decompositions exist.
