Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87432, here are decompositions:

5 + 87427 = 87432
11 + 87421 = 87432
29 + 87403 = 87432
73 + 87359 = 87432
109 + 87323 = 87432
139 + 87293 = 87432
151 + 87281 = 87432
179 + 87253 = 87432

Showing the first eight; more decompositions exist.
