Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23706, here are decompositions:

17 + 23689 = 23706
19 + 23687 = 23706
29 + 23677 = 23706
37 + 23669 = 23706
43 + 23663 = 23706
73 + 23633 = 23706
79 + 23627 = 23706
83 + 23623 = 23706

Showing the first eight; more decompositions exist.
