Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670258, here are decompositions:

19 + 8670239 = 8670258
61 + 8670197 = 8670258
67 + 8670191 = 8670258
101 + 8670157 = 8670258
131 + 8670127 = 8670258
151 + 8670107 = 8670258
227 + 8670031 = 8670258
229 + 8670029 = 8670258

Showing the first eight; more decompositions exist.
