Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630880, here are decompositions:

19 + 8630861 = 8630880
23 + 8630857 = 8630880
29 + 8630851 = 8630880
43 + 8630837 = 8630880
47 + 8630833 = 8630880
59 + 8630821 = 8630880
67 + 8630813 = 8630880
101 + 8630779 = 8630880

Showing the first eight; more decompositions exist.
