Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187156, here are decompositions:

17 + 187139 = 187156
23 + 187133 = 187156
29 + 187127 = 187156
83 + 187073 = 187156
89 + 187067 = 187156
107 + 187049 = 187156
113 + 187043 = 187156
197 + 186959 = 187156

Showing the first eight; more decompositions exist.
