Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729210, here are decompositions:

3 + 8729207 = 8729210
19 + 8729191 = 8729210
31 + 8729179 = 8729210
37 + 8729173 = 8729210
79 + 8729131 = 8729210
103 + 8729107 = 8729210
151 + 8729059 = 8729210
157 + 8729053 = 8729210

Showing the first eight; more decompositions exist.
