Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165112, here are decompositions:

23 + 165089 = 165112
29 + 165083 = 165112
53 + 165059 = 165112
71 + 165041 = 165112
113 + 164999 = 165112
149 + 164963 = 165112
281 + 164831 = 165112
383 + 164729 = 165112

Showing the first eight; more decompositions exist.
