Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729860, here are decompositions:

11 + 8729849 = 8729860
23 + 8729837 = 8729860
59 + 8729801 = 8729860
131 + 8729729 = 8729860
149 + 8729711 = 8729860
179 + 8729681 = 8729860
239 + 8729621 = 8729860
257 + 8729603 = 8729860

Showing the first eight; more decompositions exist.
