Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679240, here are decompositions:

19 + 8679221 = 8679240
23 + 8679217 = 8679240
41 + 8679199 = 8679240
47 + 8679193 = 8679240
61 + 8679179 = 8679240
103 + 8679137 = 8679240
131 + 8679109 = 8679240
181 + 8679059 = 8679240

Showing the first eight; more decompositions exist.
