Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102042, here are decompositions:

11 + 102031 = 102042
19 + 102023 = 102042
23 + 102019 = 102042
29 + 102013 = 102042
41 + 102001 = 102042
43 + 101999 = 102042
79 + 101963 = 102042
103 + 101939 = 102042

Showing the first eight; more decompositions exist.
