Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87018, here are decompositions:

5 + 87013 = 87018
7 + 87011 = 87018
37 + 86981 = 87018
59 + 86959 = 87018
67 + 86951 = 87018
79 + 86939 = 87018
89 + 86929 = 87018
149 + 86869 = 87018

Showing the first eight; more decompositions exist.
