Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505138, here are decompositions:

41 + 505097 = 505138
47 + 505091 = 505138
71 + 505067 = 505138
89 + 505049 = 505138
107 + 505031 = 505138
149 + 504989 = 505138
191 + 504947 = 505138
281 + 504857 = 505138

Showing the first eight; more decompositions exist.
