Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688968, here are decompositions:

7 + 8688961 = 8688968
139 + 8688829 = 8688968
151 + 8688817 = 8688968
181 + 8688787 = 8688968
229 + 8688739 = 8688968
271 + 8688697 = 8688968
367 + 8688601 = 8688968
397 + 8688571 = 8688968

Showing the first eight; more decompositions exist.
