Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665582, here are decompositions:

11 + 8665571 = 8665582
41 + 8665541 = 8665582
83 + 8665499 = 8665582
113 + 8665469 = 8665582
131 + 8665451 = 8665582
173 + 8665409 = 8665582
269 + 8665313 = 8665582
389 + 8665193 = 8665582

Showing the first eight; more decompositions exist.
