Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8608990, here are decompositions:

17 + 8608973 = 8608990
59 + 8608931 = 8608990
83 + 8608907 = 8608990
101 + 8608889 = 8608990
149 + 8608841 = 8608990
167 + 8608823 = 8608990
191 + 8608799 = 8608990
239 + 8608751 = 8608990

Showing the first eight; more decompositions exist.
