Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689982, here are decompositions:

3 + 8689979 = 8689982
13 + 8689969 = 8689982
139 + 8689843 = 8689982
229 + 8689753 = 8689982
271 + 8689711 = 8689982
373 + 8689609 = 8689982
409 + 8689573 = 8689982
439 + 8689543 = 8689982

Showing the first eight; more decompositions exist.
