Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020442, here are decompositions:

11 + 1020431 = 1020442
23 + 1020419 = 1020442
29 + 1020413 = 1020442
41 + 1020401 = 1020442
53 + 1020389 = 1020442
89 + 1020353 = 1020442
113 + 1020329 = 1020442
149 + 1020293 = 1020442

Showing the first eight; more decompositions exist.
