Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143448, here are decompositions:

5 + 143443 = 143448
29 + 143419 = 143448
47 + 143401 = 143448
61 + 143387 = 143448
157 + 143291 = 143448
167 + 143281 = 143448
191 + 143257 = 143448
199 + 143249 = 143448

Showing the first eight; more decompositions exist.
