Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043420, here are decompositions:

19 + 1043401 = 1043420
43 + 1043377 = 1043420
97 + 1043323 = 1043420
109 + 1043311 = 1043420
127 + 1043293 = 1043420
199 + 1043221 = 1043420
211 + 1043209 = 1043420
229 + 1043191 = 1043420

Showing the first eight; more decompositions exist.
