Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505472, here are decompositions:

3 + 505469 = 505472
13 + 505459 = 505472
43 + 505429 = 505472
61 + 505411 = 505472
73 + 505399 = 505472
103 + 505369 = 505472
151 + 505321 = 505472
193 + 505279 = 505472

Showing the first eight; more decompositions exist.
