Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27920, here are decompositions:

3 + 27917 = 27920
19 + 27901 = 27920
37 + 27883 = 27920
73 + 27847 = 27920
97 + 27823 = 27920
103 + 27817 = 27920
127 + 27793 = 27920
157 + 27763 = 27920

Showing the first eight; more decompositions exist.
