Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126042, here are decompositions:

5 + 126037 = 126042
11 + 126031 = 126042
19 + 126023 = 126042
23 + 126019 = 126042
29 + 126013 = 126042
31 + 126011 = 126042
41 + 126001 = 126042
79 + 125963 = 126042

Showing the first eight; more decompositions exist.
