Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679520, here are decompositions:

71 + 8679449 = 8679520
167 + 8679353 = 8679520
173 + 8679347 = 8679520
383 + 8679137 = 8679520
449 + 8679071 = 8679520
461 + 8679059 = 8679520
557 + 8678963 = 8679520
569 + 8678951 = 8679520

Showing the first eight; more decompositions exist.
