Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654172, here are decompositions:

61 + 8654111 = 8654172
73 + 8654099 = 8654172
83 + 8654089 = 8654172
139 + 8654033 = 8654172
151 + 8654021 = 8654172
269 + 8653903 = 8654172
281 + 8653891 = 8654172
283 + 8653889 = 8654172

Showing the first eight; more decompositions exist.
