Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10862, here are decompositions:

3 + 10859 = 10862
31 + 10831 = 10862
73 + 10789 = 10862
109 + 10753 = 10862
139 + 10723 = 10862
151 + 10711 = 10862
199 + 10663 = 10862
211 + 10651 = 10862

Showing the first eight; more decompositions exist.
