Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109918, here are decompositions:

5 + 109913 = 109918
59 + 109859 = 109918
71 + 109847 = 109918
89 + 109829 = 109918
167 + 109751 = 109918
197 + 109721 = 109918
257 + 109661 = 109918
401 + 109517 = 109918

Showing the first eight; more decompositions exist.
