Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505144, here are decompositions:

5 + 505139 = 505144
47 + 505097 = 505144
53 + 505091 = 505144
71 + 505073 = 505144
83 + 505061 = 505144
113 + 505031 = 505144
191 + 504953 = 505144
197 + 504947 = 505144

Showing the first eight; more decompositions exist.
