Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188382, here are decompositions:

13 + 188369 = 188382
23 + 188359 = 188382
31 + 188351 = 188382
59 + 188323 = 188382
71 + 188311 = 188382
79 + 188303 = 188382
83 + 188299 = 188382
101 + 188281 = 188382

Showing the first eight; more decompositions exist.
