Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186244, here are decompositions:

5 + 186239 = 186244
17 + 186227 = 186244
53 + 186191 = 186244
83 + 186161 = 186244
131 + 186113 = 186244
137 + 186107 = 186244
173 + 186071 = 186244
251 + 185993 = 186244

Showing the first eight; more decompositions exist.
