Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718582, here are decompositions:

11 + 8718571 = 8718582
43 + 8718539 = 8718582
79 + 8718503 = 8718582
113 + 8718469 = 8718582
151 + 8718431 = 8718582
163 + 8718419 = 8718582
181 + 8718401 = 8718582
233 + 8718349 = 8718582

Showing the first eight; more decompositions exist.
