Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186156, here are decompositions:

7 + 186149 = 186156
37 + 186119 = 186156
43 + 186113 = 186156
53 + 186103 = 186156
59 + 186097 = 186156
107 + 186049 = 186156
137 + 186019 = 186156
149 + 186007 = 186156

Showing the first eight; more decompositions exist.
