Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187548, here are decompositions:

17 + 187531 = 187548
41 + 187507 = 187548
71 + 187477 = 187548
79 + 187469 = 187548
107 + 187441 = 187548
131 + 187417 = 187548
139 + 187409 = 187548
181 + 187367 = 187548

Showing the first eight; more decompositions exist.
