Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043442, here are decompositions:

41 + 1043401 = 1043442
73 + 1043369 = 1043442
131 + 1043311 = 1043442
149 + 1043293 = 1043442
151 + 1043291 = 1043442
163 + 1043279 = 1043442
229 + 1043213 = 1043442
233 + 1043209 = 1043442

Showing the first eight; more decompositions exist.
