Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187754, here are decompositions:

3 + 187751 = 187754
43 + 187711 = 187754
67 + 187687 = 187754
103 + 187651 = 187754
157 + 187597 = 187754
181 + 187573 = 187754
223 + 187531 = 187754
241 + 187513 = 187754

Showing the first eight; more decompositions exist.
