Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164790, here are decompositions:

19 + 164771 = 164790
23 + 164767 = 164790
47 + 164743 = 164790
61 + 164729 = 164790
83 + 164707 = 164790
89 + 164701 = 164790
107 + 164683 = 164790
113 + 164677 = 164790

Showing the first eight; more decompositions exist.
