Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688760, here are decompositions:

53 + 8688707 = 8688760
89 + 8688671 = 8688760
131 + 8688629 = 8688760
149 + 8688611 = 8688760
167 + 8688593 = 8688760
191 + 8688569 = 8688760
233 + 8688527 = 8688760
239 + 8688521 = 8688760

Showing the first eight; more decompositions exist.
