Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026442, here are decompositions:

3 + 1026439 = 1026442
29 + 1026413 = 1026442
41 + 1026401 = 1026442
59 + 1026383 = 1026442
71 + 1026371 = 1026442
83 + 1026359 = 1026442
149 + 1026293 = 1026442
191 + 1026251 = 1026442

Showing the first eight; more decompositions exist.
