Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109940, here are decompositions:

3 + 109937 = 109940
37 + 109903 = 109940
43 + 109897 = 109940
67 + 109873 = 109940
97 + 109843 = 109940
109 + 109831 = 109940
151 + 109789 = 109940
199 + 109741 = 109940

Showing the first eight; more decompositions exist.
