Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118518, here are decompositions:

47 + 118471 = 118518
61 + 118457 = 118518
89 + 118429 = 118518
107 + 118411 = 118518
109 + 118409 = 118518
131 + 118387 = 118518
149 + 118369 = 118518
157 + 118361 = 118518

Showing the first eight; more decompositions exist.
