Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742134, here are decompositions:

13 + 8742121 = 8742134
31 + 8742103 = 8742134
67 + 8742067 = 8742134
97 + 8742037 = 8742134
151 + 8741983 = 8742134
157 + 8741977 = 8742134
211 + 8741923 = 8742134
223 + 8741911 = 8742134

Showing the first eight; more decompositions exist.
