Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742200, here are decompositions:

3 + 8742197 = 8742200
7 + 8742193 = 8742200
13 + 8742187 = 8742200
31 + 8742169 = 8742200
43 + 8742157 = 8742200
67 + 8742133 = 8742200
79 + 8742121 = 8742200
97 + 8742103 = 8742200

Showing the first eight; more decompositions exist.
