Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669438, here are decompositions:

97 + 8669341 = 8669438
109 + 8669329 = 8669438
199 + 8669239 = 8669438
331 + 8669107 = 8669438
367 + 8669071 = 8669438
397 + 8669041 = 8669438
487 + 8668951 = 8669438
541 + 8668897 = 8669438

Showing the first eight; more decompositions exist.
