Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761120, here are decompositions:

3 + 8761117 = 8761120
41 + 8761079 = 8761120
83 + 8761037 = 8761120
101 + 8761019 = 8761120
113 + 8761007 = 8761120
197 + 8760923 = 8761120
311 + 8760809 = 8761120
419 + 8760701 = 8761120

Showing the first eight; more decompositions exist.
