Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38912, here are decompositions:

61 + 38851 = 38912
73 + 38839 = 38912
79 + 38833 = 38912
109 + 38803 = 38912
163 + 38749 = 38912
199 + 38713 = 38912
241 + 38671 = 38912
283 + 38629 = 38912

Showing the first eight; more decompositions exist.
