Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187736, here are decompositions:

37 + 187699 = 187736
67 + 187669 = 187736
97 + 187639 = 187736
103 + 187633 = 187736
139 + 187597 = 187736
163 + 187573 = 187736
223 + 187513 = 187736
229 + 187507 = 187736

Showing the first eight; more decompositions exist.
