Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729212, here are decompositions:

5 + 8729207 = 8729212
29 + 8729183 = 8729212
71 + 8729141 = 8729212
113 + 8729099 = 8729212
131 + 8729081 = 8729212
179 + 8729033 = 8729212
269 + 8728943 = 8729212
311 + 8728901 = 8729212

Showing the first eight; more decompositions exist.
