Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639702, here are decompositions:

103 + 8639599 = 8639702
139 + 8639563 = 8639702
151 + 8639551 = 8639702
163 + 8639539 = 8639702
241 + 8639461 = 8639702
439 + 8639263 = 8639702
541 + 8639161 = 8639702
571 + 8639131 = 8639702

Showing the first eight; more decompositions exist.
