Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665568, here are decompositions:

7 + 8665561 = 8665568
97 + 8665471 = 8665568
127 + 8665441 = 8665568
139 + 8665429 = 8665568
199 + 8665369 = 8665568
211 + 8665357 = 8665568
349 + 8665219 = 8665568
367 + 8665201 = 8665568

Showing the first eight; more decompositions exist.
