Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712200, here are decompositions:

19 + 8712181 = 8712200
31 + 8712169 = 8712200
37 + 8712163 = 8712200
43 + 8712157 = 8712200
67 + 8712133 = 8712200
109 + 8712091 = 8712200
181 + 8712019 = 8712200
229 + 8711971 = 8712200

Showing the first eight; more decompositions exist.
