Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628084, here are decompositions:

7 + 8628077 = 8628084
53 + 8628031 = 8628084
67 + 8628017 = 8628084
97 + 8627987 = 8628084
107 + 8627977 = 8628084
131 + 8627953 = 8628084
137 + 8627947 = 8628084
173 + 8627911 = 8628084

Showing the first eight; more decompositions exist.
