Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27800, here are decompositions:

7 + 27793 = 27800
37 + 27763 = 27800
61 + 27739 = 27800
67 + 27733 = 27800
103 + 27697 = 27800
109 + 27691 = 27800
127 + 27673 = 27800
271 + 27529 = 27800

Showing the first eight; more decompositions exist.
