Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742342, here are decompositions:

29 + 8742313 = 8742342
79 + 8742263 = 8742342
83 + 8742259 = 8742342
149 + 8742193 = 8742342
173 + 8742169 = 8742342
181 + 8742161 = 8742342
239 + 8742103 = 8742342
283 + 8742059 = 8742342

Showing the first eight; more decompositions exist.
