Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679280, here are decompositions:

3 + 8679277 = 8679280
59 + 8679221 = 8679280
101 + 8679179 = 8679280
317 + 8678963 = 8679280
347 + 8678933 = 8679280
353 + 8678927 = 8679280
503 + 8678777 = 8679280
521 + 8678759 = 8679280

Showing the first eight; more decompositions exist.
