Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187852, here are decompositions:

29 + 187823 = 187852
59 + 187793 = 187852
89 + 187763 = 187852
101 + 187751 = 187852
131 + 187721 = 187852
191 + 187661 = 187852
293 + 187559 = 187852
383 + 187469 = 187852

Showing the first eight; more decompositions exist.
