Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506018, here are decompositions:

151 + 505867 = 506018
199 + 505819 = 506018
241 + 505777 = 506018
307 + 505711 = 506018
349 + 505669 = 506018
379 + 505639 = 506018
571 + 505447 = 506018
607 + 505411 = 506018

Showing the first eight; more decompositions exist.
