Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187776, here are decompositions:

13 + 187763 = 187776
89 + 187687 = 187776
107 + 187669 = 187776
137 + 187639 = 187776
139 + 187637 = 187776
179 + 187597 = 187776
229 + 187547 = 187776
263 + 187513 = 187776

Showing the first eight; more decompositions exist.
