Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669378, here are decompositions:

37 + 8669341 = 8669378
61 + 8669317 = 8669378
127 + 8669251 = 8669378
139 + 8669239 = 8669378
199 + 8669179 = 8669378
271 + 8669107 = 8669378
307 + 8669071 = 8669378
337 + 8669041 = 8669378

Showing the first eight; more decompositions exist.
