Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627432, here are decompositions:

3 + 8627429 = 8627432
61 + 8627371 = 8627432
103 + 8627329 = 8627432
181 + 8627251 = 8627432
241 + 8627191 = 8627432
271 + 8627161 = 8627432
283 + 8627149 = 8627432
313 + 8627119 = 8627432

Showing the first eight; more decompositions exist.
