Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20702, here are decompositions:

61 + 20641 = 20702
103 + 20599 = 20702
109 + 20593 = 20702
139 + 20563 = 20702
151 + 20551 = 20702
181 + 20521 = 20702
193 + 20509 = 20702
223 + 20479 = 20702

Showing the first eight; more decompositions exist.
