Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188032, here are decompositions:

3 + 188029 = 188032
11 + 188021 = 188032
59 + 187973 = 188032
101 + 187931 = 188032
149 + 187883 = 188032
239 + 187793 = 188032
269 + 187763 = 188032
281 + 187751 = 188032

Showing the first eight; more decompositions exist.
