Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755530, here are decompositions:

13 + 8755517 = 8755530
29 + 8755501 = 8755530
31 + 8755499 = 8755530
61 + 8755469 = 8755530
79 + 8755451 = 8755530
131 + 8755399 = 8755530
137 + 8755393 = 8755530
149 + 8755381 = 8755530

Showing the first eight; more decompositions exist.
