Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665592, here are decompositions:

31 + 8665561 = 8665592
151 + 8665441 = 8665592
163 + 8665429 = 8665592
223 + 8665369 = 8665592
373 + 8665219 = 8665592
571 + 8665021 = 8665592
601 + 8664991 = 8665592
613 + 8664979 = 8665592

Showing the first eight; more decompositions exist.
