Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669372, here are decompositions:

31 + 8669341 = 8669372
43 + 8669329 = 8669372
79 + 8669293 = 8669372
139 + 8669233 = 8669372
193 + 8669179 = 8669372
331 + 8669041 = 8669372
379 + 8668993 = 8669372
421 + 8668951 = 8669372

Showing the first eight; more decompositions exist.
