Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165148, here are decompositions:

59 + 165089 = 165148
89 + 165059 = 165148
101 + 165047 = 165148
107 + 165041 = 165148
149 + 164999 = 165148
311 + 164837 = 165148
317 + 164831 = 165148
359 + 164789 = 165148

Showing the first eight; more decompositions exist.
