Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109856, here are decompositions:

7 + 109849 = 109856
13 + 109843 = 109856
37 + 109819 = 109856
67 + 109789 = 109856
139 + 109717 = 109856
193 + 109663 = 109856
277 + 109579 = 109856
337 + 109519 = 109856

Showing the first eight; more decompositions exist.
