Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622880, here are decompositions:

3 + 8622877 = 8622880
23 + 8622857 = 8622880
113 + 8622767 = 8622880
173 + 8622707 = 8622880
197 + 8622683 = 8622880
269 + 8622611 = 8622880
317 + 8622563 = 8622880
359 + 8622521 = 8622880

Showing the first eight; more decompositions exist.
