Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19892, here are decompositions:

3 + 19889 = 19892
31 + 19861 = 19892
73 + 19819 = 19892
79 + 19813 = 19892
139 + 19753 = 19892
193 + 19699 = 19892
211 + 19681 = 19892
283 + 19609 = 19892

Showing the first eight; more decompositions exist.
