Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164124, here are decompositions:

7 + 164117 = 164124
11 + 164113 = 164124
31 + 164093 = 164124
53 + 164071 = 164124
67 + 164057 = 164124
73 + 164051 = 164124
101 + 164023 = 164124
113 + 164011 = 164124

Showing the first eight; more decompositions exist.
