Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689994, here are decompositions:

7 + 8689987 = 8689994
13 + 8689981 = 8689994
37 + 8689957 = 8689994
151 + 8689843 = 8689994
241 + 8689753 = 8689994
283 + 8689711 = 8689994
307 + 8689687 = 8689994
337 + 8689657 = 8689994

Showing the first eight; more decompositions exist.
