Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20150, here are decompositions:

3 + 20147 = 20150
7 + 20143 = 20150
37 + 20113 = 20150
43 + 20107 = 20150
61 + 20089 = 20150
79 + 20071 = 20150
103 + 20047 = 20150
127 + 20023 = 20150

Showing the first eight; more decompositions exist.
