Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690626, here are decompositions:

23 + 8690603 = 8690626
59 + 8690567 = 8690626
137 + 8690489 = 8690626
149 + 8690477 = 8690626
173 + 8690453 = 8690626
227 + 8690399 = 8690626
239 + 8690387 = 8690626
293 + 8690333 = 8690626

Showing the first eight; more decompositions exist.
