Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021166, here are decompositions:

7 + 1021159 = 1021166
37 + 1021129 = 1021166
43 + 1021123 = 1021166
73 + 1021093 = 1021166
79 + 1021087 = 1021166
193 + 1020973 = 1021166
199 + 1020967 = 1021166
313 + 1020853 = 1021166

Showing the first eight; more decompositions exist.
