Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639770, here are decompositions:

17 + 8639753 = 8639770
23 + 8639747 = 8639770
59 + 8639711 = 8639770
107 + 8639663 = 8639770
131 + 8639639 = 8639770
173 + 8639597 = 8639770
179 + 8639591 = 8639770
239 + 8639531 = 8639770

Showing the first eight; more decompositions exist.
