Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729662, here are decompositions:

3 + 8729659 = 8729662
41 + 8729621 = 8729662
59 + 8729603 = 8729662
233 + 8729429 = 8729662
251 + 8729411 = 8729662
353 + 8729309 = 8729662
419 + 8729243 = 8729662
443 + 8729219 = 8729662

Showing the first eight; more decompositions exist.
