Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164748, here are decompositions:

5 + 164743 = 164748
19 + 164729 = 164748
41 + 164707 = 164748
47 + 164701 = 164748
71 + 164677 = 164748
127 + 164621 = 164748
131 + 164617 = 164748
149 + 164599 = 164748

Showing the first eight; more decompositions exist.
