Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713040, here are decompositions:

3 + 8713037 = 8713040
31 + 8713009 = 8713040
43 + 8712997 = 8713040
67 + 8712973 = 8713040
109 + 8712931 = 8713040
181 + 8712859 = 8713040
283 + 8712757 = 8713040
313 + 8712727 = 8713040

Showing the first eight; more decompositions exist.
