Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688900, here are decompositions:

37 + 8688863 = 8688900
71 + 8688829 = 8688900
83 + 8688817 = 8688900
109 + 8688791 = 8688900
113 + 8688787 = 8688900
193 + 8688707 = 8688900
197 + 8688703 = 8688900
229 + 8688671 = 8688900

Showing the first eight; more decompositions exist.
