Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669508, here are decompositions:

7 + 8669501 = 8669508
19 + 8669489 = 8669508
31 + 8669477 = 8669508
61 + 8669447 = 8669508
97 + 8669411 = 8669508
109 + 8669399 = 8669508
157 + 8669351 = 8669508
167 + 8669341 = 8669508

Showing the first eight; more decompositions exist.
