Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668878, here are decompositions:

5 + 8668873 = 8668878
41 + 8668837 = 8668878
47 + 8668831 = 8668878
61 + 8668817 = 8668878
79 + 8668799 = 8668878
137 + 8668741 = 8668878
139 + 8668739 = 8668878
157 + 8668721 = 8668878

Showing the first eight; more decompositions exist.
