Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689290, here are decompositions:

7 + 8689283 = 8689290
11 + 8689279 = 8689290
17 + 8689273 = 8689290
31 + 8689259 = 8689290
41 + 8689249 = 8689290
47 + 8689243 = 8689290
67 + 8689223 = 8689290
73 + 8689217 = 8689290

Showing the first eight; more decompositions exist.
