Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42086, here are decompositions:

3 + 42083 = 42086
13 + 42073 = 42086
43 + 42043 = 42086
67 + 42019 = 42086
73 + 42013 = 42086
103 + 41983 = 42086
127 + 41959 = 42086
139 + 41947 = 42086

Showing the first eight; more decompositions exist.
