Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047158, here are decompositions:

19 + 1047139 = 1047158
31 + 1047127 = 1047158
61 + 1047097 = 1047158
97 + 1047061 = 1047158
127 + 1047031 = 1047158
181 + 1046977 = 1047158
199 + 1046959 = 1047158
241 + 1046917 = 1047158

Showing the first eight; more decompositions exist.
