Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742204, here are decompositions:

7 + 8742197 = 8742204
11 + 8742193 = 8742204
17 + 8742187 = 8742204
43 + 8742161 = 8742204
47 + 8742157 = 8742204
71 + 8742133 = 8742204
83 + 8742121 = 8742204
101 + 8742103 = 8742204

Showing the first eight; more decompositions exist.
