Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729738, here are decompositions:

79 + 8729659 = 8729738
97 + 8729641 = 8729738
109 + 8729629 = 8729738
181 + 8729557 = 8729738
271 + 8729467 = 8729738
337 + 8729401 = 8729738
349 + 8729389 = 8729738
421 + 8729317 = 8729738

Showing the first eight; more decompositions exist.
