Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27738, here are decompositions:

5 + 27733 = 27738
37 + 27701 = 27738
41 + 27697 = 27738
47 + 27691 = 27738
107 + 27631 = 27738
127 + 27611 = 27738
157 + 27581 = 27738
197 + 27541 = 27738

Showing the first eight; more decompositions exist.
