Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505448, here are decompositions:

19 + 505429 = 505448
37 + 505411 = 505448
79 + 505369 = 505448
109 + 505339 = 505448
127 + 505321 = 505448
211 + 505237 = 505448
331 + 505117 = 505448
337 + 505111 = 505448

Showing the first eight; more decompositions exist.
