Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639432, here are decompositions:

19 + 8639413 = 8639432
31 + 8639401 = 8639432
181 + 8639251 = 8639432
271 + 8639161 = 8639432
283 + 8639149 = 8639432
313 + 8639119 = 8639432
421 + 8639011 = 8639432
433 + 8638999 = 8639432

Showing the first eight; more decompositions exist.
