Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761686, here are decompositions:

47 + 8761639 = 8761686
53 + 8761633 = 8761686
67 + 8761619 = 8761686
139 + 8761547 = 8761686
149 + 8761537 = 8761686
179 + 8761507 = 8761686
223 + 8761463 = 8761686
229 + 8761457 = 8761686

Showing the first eight; more decompositions exist.
