Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8696890, here are decompositions:

23 + 8696867 = 8696890
53 + 8696837 = 8696890
101 + 8696789 = 8696890
131 + 8696759 = 8696890
179 + 8696711 = 8696890
197 + 8696693 = 8696890
227 + 8696663 = 8696890
239 + 8696651 = 8696890

Showing the first eight; more decompositions exist.
