Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20754, here are decompositions:

5 + 20749 = 20754
7 + 20747 = 20754
11 + 20743 = 20754
23 + 20731 = 20754
37 + 20717 = 20754
47 + 20707 = 20754
61 + 20693 = 20754
73 + 20681 = 20754

Showing the first eight; more decompositions exist.
