Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673142, here are decompositions:

11 + 8673131 = 8673142
29 + 8673113 = 8673142
113 + 8673029 = 8673142
131 + 8673011 = 8673142
173 + 8672969 = 8673142
251 + 8672891 = 8673142
281 + 8672861 = 8673142
311 + 8672831 = 8673142

Showing the first eight; more decompositions exist.
