Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729214, here are decompositions:

7 + 8729207 = 8729214
23 + 8729191 = 8729214
31 + 8729183 = 8729214
41 + 8729173 = 8729214
73 + 8729141 = 8729214
83 + 8729131 = 8729214
97 + 8729117 = 8729214
107 + 8729107 = 8729214

Showing the first eight; more decompositions exist.
