Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18112, here are decompositions:

23 + 18089 = 18112
53 + 18059 = 18112
71 + 18041 = 18112
131 + 17981 = 18112
173 + 17939 = 18112
191 + 17921 = 18112
383 + 17729 = 18112
431 + 17681 = 18112

Showing the first eight; more decompositions exist.
