Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130432, here are decompositions:

23 + 130409 = 130432
53 + 130379 = 130432
83 + 130349 = 130432
89 + 130343 = 130432
173 + 130259 = 130432
179 + 130253 = 130432
191 + 130241 = 130432
233 + 130199 = 130432

Showing the first eight; more decompositions exist.
