Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680744, here are decompositions:

3 + 8680741 = 8680744
11 + 8680733 = 8680744
47 + 8680697 = 8680744
53 + 8680691 = 8680744
113 + 8680631 = 8680744
131 + 8680613 = 8680744
263 + 8680481 = 8680744
353 + 8680391 = 8680744

Showing the first eight; more decompositions exist.
