Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20768, here are decompositions:

19 + 20749 = 20768
37 + 20731 = 20768
61 + 20707 = 20768
127 + 20641 = 20768
157 + 20611 = 20768
337 + 20431 = 20768
379 + 20389 = 20768
409 + 20359 = 20768

Showing the first eight; more decompositions exist.
