Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505586, here are decompositions:

13 + 505573 = 505586
73 + 505513 = 505586
127 + 505459 = 505586
139 + 505447 = 505586
157 + 505429 = 505586
229 + 505357 = 505586
307 + 505279 = 505586
349 + 505237 = 505586

Showing the first eight; more decompositions exist.
