Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27784, here are decompositions:

5 + 27779 = 27784
11 + 27773 = 27784
17 + 27767 = 27784
41 + 27743 = 27784
47 + 27737 = 27784
83 + 27701 = 27784
131 + 27653 = 27784
137 + 27647 = 27784

Showing the first eight; more decompositions exist.
