Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665530, here are decompositions:

31 + 8665499 = 8665530
59 + 8665471 = 8665530
61 + 8665469 = 8665530
79 + 8665451 = 8665530
89 + 8665441 = 8665530
101 + 8665429 = 8665530
157 + 8665373 = 8665530
173 + 8665357 = 8665530

Showing the first eight; more decompositions exist.
