Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729194, here are decompositions:

3 + 8729191 = 8729194
11 + 8729183 = 8729194
53 + 8729141 = 8729194
101 + 8729093 = 8729194
113 + 8729081 = 8729194
137 + 8729057 = 8729194
251 + 8728943 = 8729194
293 + 8728901 = 8729194

Showing the first eight; more decompositions exist.
