Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761040, here are decompositions:

3 + 8761037 = 8761040
31 + 8761009 = 8761040
139 + 8760901 = 8761040
157 + 8760883 = 8761040
163 + 8760877 = 8761040
229 + 8760811 = 8761040
241 + 8760799 = 8761040
313 + 8760727 = 8761040

Showing the first eight; more decompositions exist.
