Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667790, here are decompositions:

83 + 8667707 = 8667790
101 + 8667689 = 8667790
113 + 8667677 = 8667790
137 + 8667653 = 8667790
149 + 8667641 = 8667790
179 + 8667611 = 8667790
227 + 8667563 = 8667790
251 + 8667539 = 8667790

Showing the first eight; more decompositions exist.
