Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752420, here are decompositions:

3 + 8752417 = 8752420
41 + 8752379 = 8752420
59 + 8752361 = 8752420
167 + 8752253 = 8752420
233 + 8752187 = 8752420
239 + 8752181 = 8752420
263 + 8752157 = 8752420
353 + 8752067 = 8752420

Showing the first eight; more decompositions exist.
