Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86912, here are decompositions:

43 + 86869 = 86912
61 + 86851 = 86912
193 + 86719 = 86912
223 + 86689 = 86912
283 + 86629 = 86912
313 + 86599 = 86912
373 + 86539 = 86912
379 + 86533 = 86912

Showing the first eight; more decompositions exist.
