Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757432, here are decompositions:

23 + 8757409 = 8757432
43 + 8757389 = 8757432
53 + 8757379 = 8757432
59 + 8757373 = 8757432
163 + 8757269 = 8757432
179 + 8757253 = 8757432
223 + 8757209 = 8757432
241 + 8757191 = 8757432

Showing the first eight; more decompositions exist.
