Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040442, here are decompositions:

23 + 1040419 = 1040442
31 + 1040411 = 1040442
61 + 1040381 = 1040442
71 + 1040371 = 1040442
89 + 1040353 = 1040442
103 + 1040339 = 1040442
131 + 1040311 = 1040442
223 + 1040219 = 1040442

Showing the first eight; more decompositions exist.
