Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164448, here are decompositions:

5 + 164443 = 164448
17 + 164431 = 164448
19 + 164429 = 164448
29 + 164419 = 164448
61 + 164387 = 164448
71 + 164377 = 164448
107 + 164341 = 164448
127 + 164321 = 164448

Showing the first eight; more decompositions exist.
