Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669240, here are decompositions:

3 + 8669237 = 8669240
7 + 8669233 = 8669240
61 + 8669179 = 8669240
127 + 8669113 = 8669240
157 + 8669083 = 8669240
199 + 8669041 = 8669240
367 + 8668873 = 8669240
409 + 8668831 = 8669240

Showing the first eight; more decompositions exist.
