Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27730, here are decompositions:

29 + 27701 = 27730
41 + 27689 = 27730
83 + 27647 = 27730
113 + 27617 = 27730
149 + 27581 = 27730
179 + 27551 = 27730
191 + 27539 = 27730
251 + 27479 = 27730

Showing the first eight; more decompositions exist.
