Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620890, here are decompositions:

17 + 8620873 = 8620890
29 + 8620861 = 8620890
43 + 8620847 = 8620890
151 + 8620739 = 8620890
163 + 8620727 = 8620890
167 + 8620723 = 8620890
199 + 8620691 = 8620890
227 + 8620663 = 8620890

Showing the first eight; more decompositions exist.
