Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729932, here are decompositions:

83 + 8729849 = 8729932
131 + 8729801 = 8729932
251 + 8729681 = 8729932
311 + 8729621 = 8729932
389 + 8729543 = 8729932
503 + 8729429 = 8729932
521 + 8729411 = 8729932
599 + 8729333 = 8729932

Showing the first eight; more decompositions exist.
