Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115518, here are decompositions:

5 + 115513 = 115518
19 + 115499 = 115518
47 + 115471 = 115518
59 + 115459 = 115518
89 + 115429 = 115518
97 + 115421 = 115518
157 + 115361 = 115518
181 + 115337 = 115518

Showing the first eight; more decompositions exist.
