Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639698, here are decompositions:

59 + 8639639 = 8639698
101 + 8639597 = 8639698
107 + 8639591 = 8639698
131 + 8639567 = 8639698
149 + 8639549 = 8639698
167 + 8639531 = 8639698
191 + 8639507 = 8639698
239 + 8639459 = 8639698

Showing the first eight; more decompositions exist.
