Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118428, here are decompositions:

5 + 118423 = 118428
17 + 118411 = 118428
19 + 118409 = 118428
29 + 118399 = 118428
41 + 118387 = 118428
59 + 118369 = 118428
67 + 118361 = 118428
131 + 118297 = 118428

Showing the first eight; more decompositions exist.
