Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729394, here are decompositions:

5 + 8729389 = 8729394
61 + 8729333 = 8729394
67 + 8729327 = 8729394
71 + 8729323 = 8729394
103 + 8729291 = 8729394
151 + 8729243 = 8729394
173 + 8729221 = 8729394
211 + 8729183 = 8729394

Showing the first eight; more decompositions exist.
