Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628118, here are decompositions:

11 + 8628107 = 8628118
41 + 8628077 = 8628118
101 + 8628017 = 8628118
131 + 8627987 = 8628118
179 + 8627939 = 8628118
251 + 8627867 = 8628118
311 + 8627807 = 8628118
419 + 8627699 = 8628118

Showing the first eight; more decompositions exist.
