Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012172, here are decompositions:

13 + 1012159 = 1012172
79 + 1012093 = 1012172
163 + 1012009 = 1012172
193 + 1011979 = 1012172
199 + 1011973 = 1012172
211 + 1011961 = 1012172
229 + 1011943 = 1012172
283 + 1011889 = 1012172

Showing the first eight; more decompositions exist.
