Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628432, here are decompositions:

11 + 8628421 = 8628432
73 + 8628359 = 8628432
79 + 8628353 = 8628432
83 + 8628349 = 8628432
139 + 8628293 = 8628432
199 + 8628233 = 8628432
229 + 8628203 = 8628432
251 + 8628181 = 8628432

Showing the first eight; more decompositions exist.
