Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21774, here are decompositions:

7 + 21767 = 21774
17 + 21757 = 21774
23 + 21751 = 21774
37 + 21737 = 21774
47 + 21727 = 21774
61 + 21713 = 21774
73 + 21701 = 21774
101 + 21673 = 21774

Showing the first eight; more decompositions exist.
