Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113538, here are decompositions:

37 + 113501 = 113538
41 + 113497 = 113538
71 + 113467 = 113538
101 + 113437 = 113538
157 + 113381 = 113538
167 + 113371 = 113538
179 + 113359 = 113538
181 + 113357 = 113538

Showing the first eight; more decompositions exist.
