Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729890, here are decompositions:

3 + 8729887 = 8729890
23 + 8729867 = 8729890
41 + 8729849 = 8729890
53 + 8729837 = 8729890
89 + 8729801 = 8729890
173 + 8729717 = 8729890
179 + 8729711 = 8729890
269 + 8729621 = 8729890

Showing the first eight; more decompositions exist.
