Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729342, here are decompositions:

19 + 8729323 = 8729342
103 + 8729239 = 8729342
151 + 8729191 = 8729342
163 + 8729179 = 8729342
211 + 8729131 = 8729342
283 + 8729059 = 8729342
373 + 8728969 = 8729342
379 + 8728963 = 8729342

Showing the first eight; more decompositions exist.
