Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162090, here are decompositions:

11 + 162079 = 162090
31 + 162059 = 162090
37 + 162053 = 162090
73 + 162017 = 162090
79 + 162011 = 162090
83 + 162007 = 162090
107 + 161983 = 162090
113 + 161977 = 162090

Showing the first eight; more decompositions exist.
