Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20604, here are decompositions:

5 + 20599 = 20604
11 + 20593 = 20604
41 + 20563 = 20604
53 + 20551 = 20604
61 + 20543 = 20604
71 + 20533 = 20604
83 + 20521 = 20604
97 + 20507 = 20604

Showing the first eight; more decompositions exist.
