Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020446, here are decompositions:

67 + 1020379 = 1020446
109 + 1020337 = 1020446
199 + 1020247 = 1020446
223 + 1020223 = 1020446
283 + 1020163 = 1020446
337 + 1020109 = 1020446
367 + 1020079 = 1020446
397 + 1020049 = 1020446

Showing the first eight; more decompositions exist.
