Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689424, here are decompositions:

103 + 8689321 = 8689424
151 + 8689273 = 8689424
181 + 8689243 = 8689424
283 + 8689141 = 8689424
313 + 8689111 = 8689424
433 + 8688991 = 8689424
463 + 8688961 = 8689424
607 + 8688817 = 8689424

Showing the first eight; more decompositions exist.
