Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665598, here are decompositions:

31 + 8665567 = 8665598
37 + 8665561 = 8665598
127 + 8665471 = 8665598
157 + 8665441 = 8665598
229 + 8665369 = 8665598
241 + 8665357 = 8665598
379 + 8665219 = 8665598
397 + 8665201 = 8665598

Showing the first eight; more decompositions exist.
