Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668880, here are decompositions:

7 + 8668873 = 8668880
43 + 8668837 = 8668880
67 + 8668813 = 8668880
79 + 8668801 = 8668880
97 + 8668783 = 8668880
139 + 8668741 = 8668880
193 + 8668687 = 8668880
271 + 8668609 = 8668880

Showing the first eight; more decompositions exist.
