Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761218, here are decompositions:

5 + 8761213 = 8761218
41 + 8761177 = 8761218
61 + 8761157 = 8761218
79 + 8761139 = 8761218
101 + 8761117 = 8761218
139 + 8761079 = 8761218
181 + 8761037 = 8761218
199 + 8761019 = 8761218

Showing the first eight; more decompositions exist.
