Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940220, here are decompositions:

19 + 940201 = 940220
31 + 940189 = 940220
37 + 940183 = 940220
223 + 939997 = 940220
349 + 939871 = 940220
367 + 939853 = 940220
373 + 939847 = 940220
397 + 939823 = 940220

Showing the first eight; more decompositions exist.
