Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660258, here are decompositions:

31 + 8660227 = 8660258
37 + 8660221 = 8660258
97 + 8660161 = 8660258
151 + 8660107 = 8660258
181 + 8660077 = 8660258
331 + 8659927 = 8660258
337 + 8659921 = 8660258
349 + 8659909 = 8660258

Showing the first eight; more decompositions exist.
