Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042386, here are decompositions:

5 + 1042381 = 1042386
13 + 1042373 = 1042386
17 + 1042369 = 1042386
29 + 1042357 = 1042386
53 + 1042333 = 1042386
113 + 1042273 = 1042386
127 + 1042259 = 1042386
193 + 1042193 = 1042386

Showing the first eight; more decompositions exist.
