Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187028, here are decompositions:

19 + 187009 = 187028
139 + 186889 = 187028
151 + 186877 = 187028
157 + 186871 = 187028
229 + 186799 = 187028
271 + 186757 = 187028
349 + 186679 = 187028
379 + 186649 = 187028

Showing the first eight; more decompositions exist.
