Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606138, here are decompositions:

61 + 8606077 = 8606138
97 + 8606041 = 8606138
139 + 8605999 = 8606138
199 + 8605939 = 8606138
337 + 8605801 = 8606138
349 + 8605789 = 8606138
571 + 8605567 = 8606138
577 + 8605561 = 8606138

Showing the first eight; more decompositions exist.
