Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600138, here are decompositions:

37 + 8600101 = 8600138
67 + 8600071 = 8600138
97 + 8600041 = 8600138
109 + 8600029 = 8600138
241 + 8599897 = 8600138
271 + 8599867 = 8600138
367 + 8599771 = 8600138
571 + 8599567 = 8600138

Showing the first eight; more decompositions exist.
