Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657222, here are decompositions:

61 + 8657161 = 8657222
181 + 8657041 = 8657222
283 + 8656939 = 8657222
331 + 8656891 = 8657222
373 + 8656849 = 8657222
421 + 8656801 = 8657222
463 + 8656759 = 8657222
619 + 8656603 = 8657222

Showing the first eight; more decompositions exist.
