Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111940, here are decompositions:

47 + 111893 = 111940
71 + 111869 = 111940
83 + 111857 = 111940
107 + 111833 = 111940
113 + 111827 = 111940
149 + 111791 = 111940
167 + 111773 = 111940
173 + 111767 = 111940

Showing the first eight; more decompositions exist.
