Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505454, here are decompositions:

7 + 505447 = 505454
43 + 505411 = 505454
97 + 505357 = 505454
127 + 505327 = 505454
223 + 505231 = 505454
241 + 505213 = 505454
331 + 505123 = 505454
337 + 505117 = 505454

Showing the first eight; more decompositions exist.
