Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668562, here are decompositions:

13 + 8668549 = 8668562
43 + 8668519 = 8668562
61 + 8668501 = 8668562
73 + 8668489 = 8668562
79 + 8668483 = 8668562
103 + 8668459 = 8668562
139 + 8668423 = 8668562
181 + 8668381 = 8668562

Showing the first eight; more decompositions exist.
