Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20104, here are decompositions:

3 + 20101 = 20104
41 + 20063 = 20104
53 + 20051 = 20104
83 + 20021 = 20104
107 + 19997 = 20104
113 + 19991 = 20104
131 + 19973 = 20104
167 + 19937 = 20104

Showing the first eight; more decompositions exist.
