Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729926, here are decompositions:

3 + 8729923 = 8729926
59 + 8729867 = 8729926
89 + 8729837 = 8729926
197 + 8729729 = 8729926
383 + 8729543 = 8729926
593 + 8729333 = 8729926
599 + 8729327 = 8729926
617 + 8729309 = 8729926

Showing the first eight; more decompositions exist.
