Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663408, here are decompositions:

7 + 8663401 = 8663408
97 + 8663311 = 8663408
199 + 8663209 = 8663408
307 + 8663101 = 8663408
337 + 8663071 = 8663408
421 + 8662987 = 8663408
541 + 8662867 = 8663408
577 + 8662831 = 8663408

Showing the first eight; more decompositions exist.
