Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109978, here are decompositions:

17 + 109961 = 109978
41 + 109937 = 109978
59 + 109919 = 109978
131 + 109847 = 109978
137 + 109841 = 109978
149 + 109829 = 109978
227 + 109751 = 109978
257 + 109721 = 109978

Showing the first eight; more decompositions exist.
