Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688940, here are decompositions:

131 + 8688809 = 8688940
149 + 8688791 = 8688940
233 + 8688707 = 8688940
269 + 8688671 = 8688940
311 + 8688629 = 8688940
347 + 8688593 = 8688940
383 + 8688557 = 8688940
389 + 8688551 = 8688940

Showing the first eight; more decompositions exist.
