Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723882, here are decompositions:

3 + 8723879 = 8723882
31 + 8723851 = 8723882
61 + 8723821 = 8723882
151 + 8723731 = 8723882
229 + 8723653 = 8723882
313 + 8723569 = 8723882
331 + 8723551 = 8723882
463 + 8723419 = 8723882

Showing the first eight; more decompositions exist.
