Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729492, here are decompositions:

103 + 8729389 = 8729492
271 + 8729221 = 8729492
313 + 8729179 = 8729492
433 + 8729059 = 8729492
439 + 8729053 = 8729492
523 + 8728969 = 8729492
571 + 8728921 = 8729492
643 + 8728849 = 8729492

Showing the first eight; more decompositions exist.
