Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020438, here are decompositions:

7 + 1020431 = 1020438
19 + 1020419 = 1020438
31 + 1020407 = 1020438
37 + 1020401 = 1020438
59 + 1020379 = 1020438
101 + 1020337 = 1020438
109 + 1020329 = 1020438
137 + 1020301 = 1020438

Showing the first eight; more decompositions exist.
