Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186944, here are decompositions:

61 + 186883 = 186944
67 + 186877 = 186944
73 + 186871 = 186944
103 + 186841 = 186944
151 + 186793 = 186944
181 + 186763 = 186944
211 + 186733 = 186944
463 + 186481 = 186944

Showing the first eight; more decompositions exist.
