Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27826, here are decompositions:

3 + 27823 = 27826
17 + 27809 = 27826
23 + 27803 = 27826
47 + 27779 = 27826
53 + 27773 = 27826
59 + 27767 = 27826
83 + 27743 = 27826
89 + 27737 = 27826

Showing the first eight; more decompositions exist.
