Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42042, here are decompositions:

19 + 42023 = 42042
23 + 42019 = 42042
29 + 42013 = 42042
43 + 41999 = 42042
59 + 41983 = 42042
61 + 41981 = 42042
73 + 41969 = 42042
83 + 41959 = 42042

Showing the first eight; more decompositions exist.
