Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702550, here are decompositions:

7 + 8702543 = 8702550
11 + 8702539 = 8702550
47 + 8702503 = 8702550
53 + 8702497 = 8702550
61 + 8702489 = 8702550
67 + 8702483 = 8702550
139 + 8702411 = 8702550
163 + 8702387 = 8702550

Showing the first eight; more decompositions exist.
