Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188412, here are decompositions:

5 + 188407 = 188412
11 + 188401 = 188412
23 + 188389 = 188412
43 + 188369 = 188412
53 + 188359 = 188412
61 + 188351 = 188412
79 + 188333 = 188412
89 + 188323 = 188412

Showing the first eight; more decompositions exist.
