Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987824, here are decompositions:

3 + 987821 = 987824
31 + 987793 = 987824
127 + 987697 = 987824
193 + 987631 = 987824
283 + 987541 = 987824
367 + 987457 = 987824
433 + 987391 = 987824
463 + 987361 = 987824

Showing the first eight; more decompositions exist.
