Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724200, here are decompositions:

19 + 8724181 = 8724200
31 + 8724169 = 8724200
61 + 8724139 = 8724200
73 + 8724127 = 8724200
127 + 8724073 = 8724200
223 + 8723977 = 8724200
271 + 8723929 = 8724200
307 + 8723893 = 8724200

Showing the first eight; more decompositions exist.
