Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505078, here are decompositions:

5 + 505073 = 505078
11 + 505067 = 505078
17 + 505061 = 505078
29 + 505049 = 505078
47 + 505031 = 505078
89 + 504989 = 505078
131 + 504947 = 505078
149 + 504929 = 505078

Showing the first eight; more decompositions exist.
