Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688744, here are decompositions:

5 + 8688739 = 8688744
37 + 8688707 = 8688744
41 + 8688703 = 8688744
47 + 8688697 = 8688744
73 + 8688671 = 8688744
131 + 8688613 = 8688744
137 + 8688607 = 8688744
151 + 8688593 = 8688744

Showing the first eight; more decompositions exist.
