Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165448, here are decompositions:

5 + 165443 = 165448
11 + 165437 = 165448
131 + 165317 = 165448
137 + 165311 = 165448
359 + 165089 = 165448
389 + 165059 = 165448
401 + 165047 = 165448
449 + 164999 = 165448

Showing the first eight; more decompositions exist.
