Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618028, here are decompositions:

7 + 8618021 = 8618028
37 + 8617991 = 8618028
79 + 8617949 = 8618028
101 + 8617927 = 8618028
151 + 8617877 = 8618028
157 + 8617871 = 8618028
191 + 8617837 = 8618028
229 + 8617799 = 8618028

Showing the first eight; more decompositions exist.
