Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187658, here are decompositions:

7 + 187651 = 187658
19 + 187639 = 187658
61 + 187597 = 187658
127 + 187531 = 187658
151 + 187507 = 187658
181 + 187477 = 187658
241 + 187417 = 187658
271 + 187387 = 187658

Showing the first eight; more decompositions exist.
