Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187574, here are decompositions:

43 + 187531 = 187574
61 + 187513 = 187574
67 + 187507 = 187574
97 + 187477 = 187574
103 + 187471 = 187574
151 + 187423 = 187574
157 + 187417 = 187574
181 + 187393 = 187574

Showing the first eight; more decompositions exist.
