Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729292, here are decompositions:

43 + 8729249 = 8729292
53 + 8729239 = 8729292
71 + 8729221 = 8729292
73 + 8729219 = 8729292
101 + 8729191 = 8729292
109 + 8729183 = 8729292
113 + 8729179 = 8729292
151 + 8729141 = 8729292

Showing the first eight; more decompositions exist.
