Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663444, here are decompositions:

3 + 8663441 = 8663444
7 + 8663437 = 8663444
43 + 8663401 = 8663444
373 + 8663071 = 8663444
421 + 8663023 = 8663444
457 + 8662987 = 8663444
577 + 8662867 = 8663444
613 + 8662831 = 8663444

Showing the first eight; more decompositions exist.
