Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752042, here are decompositions:

3 + 8752039 = 8752042
11 + 8752031 = 8752042
179 + 8751863 = 8752042
239 + 8751803 = 8752042
269 + 8751773 = 8752042
293 + 8751749 = 8752042
443 + 8751599 = 8752042
449 + 8751593 = 8752042

Showing the first eight; more decompositions exist.
