Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187568, here are decompositions:

37 + 187531 = 187568
61 + 187507 = 187568
97 + 187471 = 187568
127 + 187441 = 187568
151 + 187417 = 187568
181 + 187387 = 187568
229 + 187339 = 187568
331 + 187237 = 187568

Showing the first eight; more decompositions exist.
