Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5806, here are decompositions:

5 + 5801 = 5806
23 + 5783 = 5806
89 + 5717 = 5806
113 + 5693 = 5806
137 + 5669 = 5806
149 + 5657 = 5806
167 + 5639 = 5806
233 + 5573 = 5806

Showing the first eight; more decompositions exist.
