Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042458, here are decompositions:

7 + 1042451 = 1042458
19 + 1042439 = 1042458
31 + 1042427 = 1042458
59 + 1042399 = 1042458
89 + 1042369 = 1042458
101 + 1042357 = 1042458
127 + 1042331 = 1042458
149 + 1042309 = 1042458

Showing the first eight; more decompositions exist.
