Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187700, here are decompositions:

13 + 187687 = 187700
31 + 187669 = 187700
61 + 187639 = 187700
67 + 187633 = 187700
103 + 187597 = 187700
127 + 187573 = 187700
193 + 187507 = 187700
223 + 187477 = 187700

Showing the first eight; more decompositions exist.
