Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667520, here are decompositions:

23 + 8667497 = 8667520
89 + 8667431 = 8667520
101 + 8667419 = 8667520
107 + 8667413 = 8667520
149 + 8667371 = 8667520
263 + 8667257 = 8667520
293 + 8667227 = 8667520
353 + 8667167 = 8667520

Showing the first eight; more decompositions exist.
