Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669898, here are decompositions:

5 + 8669893 = 8669898
19 + 8669879 = 8669898
37 + 8669861 = 8669898
67 + 8669831 = 8669898
131 + 8669767 = 8669898
197 + 8669701 = 8669898
227 + 8669671 = 8669898
229 + 8669669 = 8669898

Showing the first eight; more decompositions exist.
