Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188002, here are decompositions:

29 + 187973 = 188002
71 + 187931 = 188002
131 + 187871 = 188002
179 + 187823 = 188002
239 + 187763 = 188002
251 + 187751 = 188002
281 + 187721 = 188002
443 + 187559 = 188002

Showing the first eight; more decompositions exist.
