Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187650, here are decompositions:

11 + 187639 = 187650
13 + 187637 = 187650
17 + 187633 = 187650
19 + 187631 = 187650
53 + 187597 = 187650
103 + 187547 = 187650
137 + 187513 = 187650
173 + 187477 = 187650

Showing the first eight; more decompositions exist.
