Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722166, here are decompositions:

43 + 8722123 = 8722166
67 + 8722099 = 8722166
73 + 8722093 = 8722166
139 + 8722027 = 8722166
157 + 8722009 = 8722166
283 + 8721883 = 8722166
499 + 8721667 = 8722166
787 + 8721379 = 8722166

Showing the first eight; more decompositions exist.
