Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20630, here are decompositions:

3 + 20627 = 20630
19 + 20611 = 20630
31 + 20599 = 20630
37 + 20593 = 20630
67 + 20563 = 20630
79 + 20551 = 20630
97 + 20533 = 20630
109 + 20521 = 20630

Showing the first eight; more decompositions exist.
