Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729038, here are decompositions:

5 + 8729033 = 8729038
137 + 8728901 = 8729038
251 + 8728787 = 8729038
281 + 8728757 = 8729038
317 + 8728721 = 8729038
347 + 8728691 = 8729038
359 + 8728679 = 8729038
389 + 8728649 = 8729038

Showing the first eight; more decompositions exist.
