Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87030, here are decompositions:

17 + 87013 = 87030
19 + 87011 = 87030
37 + 86993 = 87030
61 + 86969 = 87030
71 + 86959 = 87030
79 + 86951 = 87030
101 + 86929 = 87030
103 + 86927 = 87030

Showing the first eight; more decompositions exist.
