Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661698, here are decompositions:

127 + 8661571 = 8661698
211 + 8661487 = 8661698
229 + 8661469 = 8661698
271 + 8661427 = 8661698
457 + 8661241 = 8661698
751 + 8660947 = 8661698
769 + 8660929 = 8661698
811 + 8660887 = 8661698

Showing the first eight; more decompositions exist.
