Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42090, here are decompositions:

7 + 42083 = 42090
17 + 42073 = 42090
19 + 42071 = 42090
29 + 42061 = 42090
47 + 42043 = 42090
67 + 42023 = 42090
71 + 42019 = 42090
73 + 42017 = 42090

Showing the first eight; more decompositions exist.
