Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20046, here are decompositions:

17 + 20029 = 20046
23 + 20023 = 20046
53 + 19993 = 20046
67 + 19979 = 20046
73 + 19973 = 20046
83 + 19963 = 20046
97 + 19949 = 20046
109 + 19937 = 20046

Showing the first eight; more decompositions exist.
