Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729032, here are decompositions:

89 + 8728943 = 8729032
131 + 8728901 = 8729032
149 + 8728883 = 8729032
311 + 8728721 = 8729032
353 + 8728679 = 8729032
383 + 8728649 = 8729032
461 + 8728571 = 8729032
659 + 8728373 = 8729032

Showing the first eight; more decompositions exist.
