Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663642, here are decompositions:

139 + 8663503 = 8663642
181 + 8663461 = 8663642
241 + 8663401 = 8663642
331 + 8663311 = 8663642
433 + 8663209 = 8663642
523 + 8663119 = 8663642
541 + 8663101 = 8663642
571 + 8663071 = 8663642

Showing the first eight; more decompositions exist.
