Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 36810, here are decompositions:

17 + 36793 = 36810
19 + 36791 = 36810
23 + 36787 = 36810
29 + 36781 = 36810
31 + 36779 = 36810
43 + 36767 = 36810
61 + 36749 = 36810
71 + 36739 = 36810

Showing the first eight; more decompositions exist.
