Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761210, here are decompositions:

41 + 8761169 = 8761210
53 + 8761157 = 8761210
71 + 8761139 = 8761210
131 + 8761079 = 8761210
173 + 8761037 = 8761210
191 + 8761019 = 8761210
233 + 8760977 = 8761210
251 + 8760959 = 8761210

Showing the first eight; more decompositions exist.
