Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689980, here are decompositions:

11 + 8689969 = 8689980
23 + 8689957 = 8689980
31 + 8689949 = 8689980
37 + 8689943 = 8689980
127 + 8689853 = 8689980
137 + 8689843 = 8689980
139 + 8689841 = 8689980
157 + 8689823 = 8689980

Showing the first eight; more decompositions exist.
