Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20634, here are decompositions:

7 + 20627 = 20634
23 + 20611 = 20634
41 + 20593 = 20634
71 + 20563 = 20634
83 + 20551 = 20634
101 + 20533 = 20634
113 + 20521 = 20634
127 + 20507 = 20634

Showing the first eight; more decompositions exist.
