Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742234, here are decompositions:

37 + 8742197 = 8742234
41 + 8742193 = 8742234
47 + 8742187 = 8742234
73 + 8742161 = 8742234
101 + 8742133 = 8742234
113 + 8742121 = 8742234
131 + 8742103 = 8742234
157 + 8742077 = 8742234

Showing the first eight; more decompositions exist.
