Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188104, here are decompositions:

83 + 188021 = 188104
131 + 187973 = 188104
173 + 187931 = 188104
197 + 187907 = 188104
227 + 187877 = 188104
233 + 187871 = 188104
281 + 187823 = 188104
311 + 187793 = 188104

Showing the first eight; more decompositions exist.
