Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505180, here are decompositions:

23 + 505157 = 505180
41 + 505139 = 505180
83 + 505097 = 505180
89 + 505091 = 505180
107 + 505073 = 505180
113 + 505067 = 505180
131 + 505049 = 505180
149 + 505031 = 505180

Showing the first eight; more decompositions exist.
