Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505202, here are decompositions:

43 + 505159 = 505202
73 + 505129 = 505202
79 + 505123 = 505202
151 + 505051 = 505202
211 + 504991 = 505202
331 + 504871 = 505202
349 + 504853 = 505202
541 + 504661 = 505202

Showing the first eight; more decompositions exist.
