Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021226, here are decompositions:

43 + 1021183 = 1021226
67 + 1021159 = 1021226
97 + 1021129 = 1021226
103 + 1021123 = 1021226
139 + 1021087 = 1021226
229 + 1020997 = 1021226
313 + 1020913 = 1021226
373 + 1020853 = 1021226

Showing the first eight; more decompositions exist.
