Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505204, here are decompositions:

3 + 505201 = 505204
17 + 505187 = 505204
23 + 505181 = 505204
47 + 505157 = 505204
107 + 505097 = 505204
113 + 505091 = 505204
131 + 505073 = 505204
137 + 505067 = 505204

Showing the first eight; more decompositions exist.
