Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188028, here are decompositions:

7 + 188021 = 188028
11 + 188017 = 188028
17 + 188011 = 188028
41 + 187987 = 188028
97 + 187931 = 188028
101 + 187927 = 188028
107 + 187921 = 188028
131 + 187897 = 188028

Showing the first eight; more decompositions exist.
