Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111172, here are decompositions:

23 + 111149 = 111172
29 + 111143 = 111172
53 + 111119 = 111172
233 + 110939 = 111172
239 + 110933 = 111172
251 + 110921 = 111172
263 + 110909 = 111172
293 + 110879 = 111172

Showing the first eight; more decompositions exist.
