Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180448, here are decompositions:

11 + 180437 = 180448
29 + 180419 = 180448
101 + 180347 = 180448
131 + 180317 = 180448
137 + 180311 = 180448
167 + 180281 = 180448
227 + 180221 = 180448
269 + 180179 = 180448

Showing the first eight; more decompositions exist.
