Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27880, here are decompositions:

29 + 27851 = 27880
53 + 27827 = 27880
71 + 27809 = 27880
89 + 27791 = 27880
101 + 27779 = 27880
107 + 27773 = 27880
113 + 27767 = 27880
131 + 27749 = 27880

Showing the first eight; more decompositions exist.
