Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669626, here are decompositions:

3 + 8669623 = 8669626
5 + 8669621 = 8669626
83 + 8669543 = 8669626
113 + 8669513 = 8669626
137 + 8669489 = 8669626
149 + 8669477 = 8669626
179 + 8669447 = 8669626
227 + 8669399 = 8669626

Showing the first eight; more decompositions exist.
