Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742332, here are decompositions:

19 + 8742313 = 8742332
73 + 8742259 = 8742332
139 + 8742193 = 8742332
163 + 8742169 = 8742332
199 + 8742133 = 8742332
211 + 8742121 = 8742332
229 + 8742103 = 8742332
349 + 8741983 = 8742332

Showing the first eight; more decompositions exist.
