Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761180, here are decompositions:

3 + 8761177 = 8761180
11 + 8761169 = 8761180
23 + 8761157 = 8761180
41 + 8761139 = 8761180
47 + 8761133 = 8761180
101 + 8761079 = 8761180
173 + 8761007 = 8761180
257 + 8760923 = 8761180

Showing the first eight; more decompositions exist.
