Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729318, here are decompositions:

79 + 8729239 = 8729318
97 + 8729221 = 8729318
127 + 8729191 = 8729318
139 + 8729179 = 8729318
211 + 8729107 = 8729318
331 + 8728987 = 8729318
349 + 8728969 = 8729318
397 + 8728921 = 8729318

Showing the first eight; more decompositions exist.
