Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663558, here are decompositions:

37 + 8663521 = 8663558
61 + 8663497 = 8663558
97 + 8663461 = 8663558
157 + 8663401 = 8663558
349 + 8663209 = 8663558
439 + 8663119 = 8663558
457 + 8663101 = 8663558
487 + 8663071 = 8663558

Showing the first eight; more decompositions exist.
