Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648432, here are decompositions:

19 + 8648413 = 8648432
43 + 8648389 = 8648432
61 + 8648371 = 8648432
109 + 8648323 = 8648432
181 + 8648251 = 8648432
193 + 8648239 = 8648432
211 + 8648221 = 8648432
241 + 8648191 = 8648432

Showing the first eight; more decompositions exist.
