Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27750, here are decompositions:

7 + 27743 = 27750
11 + 27739 = 27750
13 + 27737 = 27750
17 + 27733 = 27750
53 + 27697 = 27750
59 + 27691 = 27750
61 + 27689 = 27750
97 + 27653 = 27750

Showing the first eight; more decompositions exist.
