Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187604, here are decompositions:

7 + 187597 = 187604
31 + 187573 = 187604
73 + 187531 = 187604
97 + 187507 = 187604
127 + 187477 = 187604
163 + 187441 = 187604
181 + 187423 = 187604
211 + 187393 = 187604

Showing the first eight; more decompositions exist.
