Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505718, here are decompositions:

7 + 505711 = 505718
61 + 505657 = 505718
79 + 505639 = 505718
181 + 505537 = 505718
271 + 505447 = 505718
307 + 505411 = 505718
349 + 505369 = 505718
379 + 505339 = 505718

Showing the first eight; more decompositions exist.
