Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505498, here are decompositions:

5 + 505493 = 505498
17 + 505481 = 505498
29 + 505469 = 505498
89 + 505409 = 505498
131 + 505367 = 505498
179 + 505319 = 505498
197 + 505301 = 505498
311 + 505187 = 505498

Showing the first eight; more decompositions exist.
