Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736686, here are decompositions:

3 + 8736683 = 8736686
19 + 8736667 = 8736686
103 + 8736583 = 8736686
139 + 8736547 = 8736686
157 + 8736529 = 8736686
223 + 8736463 = 8736686
463 + 8736223 = 8736686
487 + 8736199 = 8736686

Showing the first eight; more decompositions exist.
