Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742146, here are decompositions:

13 + 8742133 = 8742146
43 + 8742103 = 8742146
79 + 8742067 = 8742146
109 + 8742037 = 8742146
157 + 8741989 = 8742146
163 + 8741983 = 8742146
199 + 8741947 = 8742146
223 + 8741923 = 8742146

Showing the first eight; more decompositions exist.
