Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105566, here are decompositions:

3 + 105563 = 105566
37 + 105529 = 105566
67 + 105499 = 105566
193 + 105373 = 105566
199 + 105367 = 105566
229 + 105337 = 105566
313 + 105253 = 105566
337 + 105229 = 105566

Showing the first eight; more decompositions exist.
