Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629432, here are decompositions:

3 + 8629429 = 8629432
23 + 8629409 = 8629432
83 + 8629349 = 8629432
89 + 8629343 = 8629432
191 + 8629241 = 8629432
233 + 8629199 = 8629432
239 + 8629193 = 8629432
263 + 8629169 = 8629432

Showing the first eight; more decompositions exist.
