Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188340, here are decompositions:

7 + 188333 = 188340
17 + 188323 = 188340
23 + 188317 = 188340
29 + 188311 = 188340
37 + 188303 = 188340
41 + 188299 = 188340
59 + 188281 = 188340
67 + 188273 = 188340

Showing the first eight; more decompositions exist.
