Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20110, here are decompositions:

3 + 20107 = 20110
47 + 20063 = 20110
59 + 20051 = 20110
89 + 20021 = 20110
113 + 19997 = 20110
131 + 19979 = 20110
137 + 19973 = 20110
149 + 19961 = 20110

Showing the first eight; more decompositions exist.
