Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657492, here are decompositions:

31 + 8657461 = 8657492
43 + 8657449 = 8657492
61 + 8657431 = 8657492
271 + 8657221 = 8657492
331 + 8657161 = 8657492
439 + 8657053 = 8657492
601 + 8656891 = 8657492
643 + 8656849 = 8657492

Showing the first eight; more decompositions exist.
