Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42018, here are decompositions:

5 + 42013 = 42018
19 + 41999 = 42018
37 + 41981 = 42018
59 + 41959 = 42018
61 + 41957 = 42018
71 + 41947 = 42018
107 + 41911 = 42018
131 + 41887 = 42018

Showing the first eight; more decompositions exist.
