Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20672, here are decompositions:

31 + 20641 = 20672
61 + 20611 = 20672
73 + 20599 = 20672
79 + 20593 = 20672
109 + 20563 = 20672
139 + 20533 = 20672
151 + 20521 = 20672
163 + 20509 = 20672

Showing the first eight; more decompositions exist.
