Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30432, here are decompositions:

5 + 30427 = 30432
29 + 30403 = 30432
41 + 30391 = 30432
43 + 30389 = 30432
109 + 30323 = 30432
113 + 30319 = 30432
139 + 30293 = 30432
163 + 30269 = 30432

Showing the first eight; more decompositions exist.
