Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27748, here are decompositions:

5 + 27743 = 27748
11 + 27737 = 27748
47 + 27701 = 27748
59 + 27689 = 27748
101 + 27647 = 27748
131 + 27617 = 27748
137 + 27611 = 27748
167 + 27581 = 27748

Showing the first eight; more decompositions exist.
