Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618040, here are decompositions:

7 + 8618033 = 8618040
19 + 8618021 = 8618040
47 + 8617993 = 8618040
97 + 8617943 = 8618040
107 + 8617933 = 8618040
113 + 8617927 = 8618040
163 + 8617877 = 8618040
241 + 8617799 = 8618040

Showing the first eight; more decompositions exist.
