Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187766, here are decompositions:

3 + 187763 = 187766
67 + 187699 = 187766
79 + 187687 = 187766
97 + 187669 = 187766
127 + 187639 = 187766
193 + 187573 = 187766
349 + 187417 = 187766
373 + 187393 = 187766

Showing the first eight; more decompositions exist.
