Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40030, here are decompositions:

17 + 40013 = 40030
41 + 39989 = 40030
47 + 39983 = 40030
59 + 39971 = 40030
101 + 39929 = 40030
167 + 39863 = 40030
173 + 39857 = 40030
191 + 39839 = 40030

Showing the first eight; more decompositions exist.
