Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042166, here are decompositions:

43 + 1042123 = 1042166
67 + 1042099 = 1042166
79 + 1042087 = 1042166
127 + 1042039 = 1042166
277 + 1041889 = 1042166
313 + 1041853 = 1042166
337 + 1041829 = 1042166
373 + 1041793 = 1042166

Showing the first eight; more decompositions exist.
