Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700432, here are decompositions:

11 + 8700421 = 8700432
31 + 8700401 = 8700432
71 + 8700361 = 8700432
79 + 8700353 = 8700432
149 + 8700283 = 8700432
151 + 8700281 = 8700432
179 + 8700253 = 8700432
193 + 8700239 = 8700432

Showing the first eight; more decompositions exist.
