Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761090, here are decompositions:

11 + 8761079 = 8761090
53 + 8761037 = 8761090
71 + 8761019 = 8761090
83 + 8761007 = 8761090
113 + 8760977 = 8761090
131 + 8760959 = 8761090
167 + 8760923 = 8761090
179 + 8760911 = 8761090

Showing the first eight; more decompositions exist.
