Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628190, here are decompositions:

3 + 8628187 = 8628190
17 + 8628173 = 8628190
29 + 8628161 = 8628190
41 + 8628149 = 8628190
59 + 8628131 = 8628190
83 + 8628107 = 8628190
113 + 8628077 = 8628190
173 + 8628017 = 8628190

Showing the first eight; more decompositions exist.
