Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112518, here are decompositions:

11 + 112507 = 112518
17 + 112501 = 112518
37 + 112481 = 112518
59 + 112459 = 112518
89 + 112429 = 112518
157 + 112361 = 112518
179 + 112339 = 112518
181 + 112337 = 112518

Showing the first eight; more decompositions exist.
