Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187774, here are decompositions:

11 + 187763 = 187774
23 + 187751 = 187774
53 + 187721 = 187774
113 + 187661 = 187774
137 + 187637 = 187774
227 + 187547 = 187774
311 + 187463 = 187774
401 + 187373 = 187774

Showing the first eight; more decompositions exist.
