Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505982, here are decompositions:

3 + 505979 = 505982
13 + 505969 = 505982
163 + 505819 = 505982
223 + 505759 = 505982
271 + 505711 = 505982
313 + 505669 = 505982
349 + 505633 = 505982
409 + 505573 = 505982

Showing the first eight; more decompositions exist.
