Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688740, here are decompositions:

37 + 8688703 = 8688740
43 + 8688697 = 8688740
127 + 8688613 = 8688740
139 + 8688601 = 8688740
157 + 8688583 = 8688740
163 + 8688577 = 8688740
271 + 8688469 = 8688740
331 + 8688409 = 8688740

Showing the first eight; more decompositions exist.
