Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758880, here are decompositions:

3 + 8758877 = 8758880
19 + 8758861 = 8758880
61 + 8758819 = 8758880
79 + 8758801 = 8758880
103 + 8758777 = 8758880
211 + 8758669 = 8758880
283 + 8758597 = 8758880
307 + 8758573 = 8758880

Showing the first eight; more decompositions exist.
