Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86988, here are decompositions:

7 + 86981 = 86988
19 + 86969 = 86988
29 + 86959 = 86988
37 + 86951 = 86988
59 + 86929 = 86988
61 + 86927 = 86988
127 + 86861 = 86988
131 + 86857 = 86988

Showing the first eight; more decompositions exist.
