Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20894, here are decompositions:

7 + 20887 = 20894
37 + 20857 = 20894
151 + 20743 = 20894
163 + 20731 = 20894
283 + 20611 = 20894
331 + 20563 = 20894
373 + 20521 = 20894
463 + 20431 = 20894

Showing the first eight; more decompositions exist.
