Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669648, here are decompositions:

19 + 8669629 = 8669648
37 + 8669611 = 8669648
307 + 8669341 = 8669648
331 + 8669317 = 8669648
397 + 8669251 = 8669648
409 + 8669239 = 8669648
541 + 8669107 = 8669648
577 + 8669071 = 8669648

Showing the first eight; more decompositions exist.
