Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729612, here are decompositions:

19 + 8729593 = 8729612
211 + 8729401 = 8729612
223 + 8729389 = 8729612
373 + 8729239 = 8729612
421 + 8729191 = 8729612
433 + 8729179 = 8729612
439 + 8729173 = 8729612
643 + 8728969 = 8729612

Showing the first eight; more decompositions exist.
