Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712198, here are decompositions:

17 + 8712181 = 8712198
29 + 8712169 = 8712198
31 + 8712167 = 8712198
41 + 8712157 = 8712198
107 + 8712091 = 8712198
139 + 8712059 = 8712198
179 + 8712019 = 8712198
181 + 8712017 = 8712198

Showing the first eight; more decompositions exist.
