Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628090, here are decompositions:

13 + 8628077 = 8628090
41 + 8628049 = 8628090
59 + 8628031 = 8628090
71 + 8628019 = 8628090
73 + 8628017 = 8628090
83 + 8628007 = 8628090
103 + 8627987 = 8628090
113 + 8627977 = 8628090

Showing the first eight; more decompositions exist.
