Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505430, here are decompositions:

19 + 505411 = 505430
31 + 505399 = 505430
61 + 505369 = 505430
73 + 505357 = 505430
103 + 505327 = 505430
109 + 505321 = 505430
151 + 505279 = 505430
193 + 505237 = 505430

Showing the first eight; more decompositions exist.
