Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761270, here are decompositions:

17 + 8761253 = 8761270
101 + 8761169 = 8761270
113 + 8761157 = 8761270
131 + 8761139 = 8761270
137 + 8761133 = 8761270
191 + 8761079 = 8761270
233 + 8761037 = 8761270
251 + 8761019 = 8761270

Showing the first eight; more decompositions exist.
