Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505376, here are decompositions:

7 + 505369 = 505376
19 + 505357 = 505376
37 + 505339 = 505376
97 + 505279 = 505376
139 + 505237 = 505376
163 + 505213 = 505376
349 + 505027 = 505376
409 + 504967 = 505376

Showing the first eight; more decompositions exist.
