Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187608, here are decompositions:

11 + 187597 = 187608
61 + 187547 = 187608
101 + 187507 = 187608
131 + 187477 = 187608
137 + 187471 = 187608
139 + 187469 = 187608
167 + 187441 = 187608
191 + 187417 = 187608

Showing the first eight; more decompositions exist.
