Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20694, here are decompositions:

13 + 20681 = 20694
31 + 20663 = 20694
53 + 20641 = 20694
67 + 20627 = 20694
83 + 20611 = 20694
101 + 20593 = 20694
131 + 20563 = 20694
151 + 20543 = 20694

Showing the first eight; more decompositions exist.
