Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742276, here are decompositions:

13 + 8742263 = 8742276
17 + 8742259 = 8742276
79 + 8742197 = 8742276
83 + 8742193 = 8742276
89 + 8742187 = 8742276
107 + 8742169 = 8742276
173 + 8742103 = 8742276
199 + 8742077 = 8742276

Showing the first eight; more decompositions exist.
