Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689020, here are decompositions:

23 + 8688997 = 8689020
29 + 8688991 = 8689020
59 + 8688961 = 8689020
101 + 8688919 = 8689020
157 + 8688863 = 8689020
191 + 8688829 = 8689020
211 + 8688809 = 8689020
229 + 8688791 = 8689020

Showing the first eight; more decompositions exist.
