Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689964, here are decompositions:

7 + 8689957 = 8689964
211 + 8689753 = 8689964
277 + 8689687 = 8689964
307 + 8689657 = 8689964
337 + 8689627 = 8689964
373 + 8689591 = 8689964
421 + 8689543 = 8689964
643 + 8689321 = 8689964

Showing the first eight; more decompositions exist.
