Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605940, here are decompositions:

67 + 8605873 = 8605940
97 + 8605843 = 8605940
127 + 8605813 = 8605940
139 + 8605801 = 8605940
151 + 8605789 = 8605940
331 + 8605609 = 8605940
373 + 8605567 = 8605940
379 + 8605561 = 8605940

Showing the first eight; more decompositions exist.
