Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509202, here are decompositions:

53 + 509149 = 509202
79 + 509123 = 509202
101 + 509101 = 509202
131 + 509071 = 509202
139 + 509063 = 509202
149 + 509053 = 509202
179 + 509023 = 509202
229 + 508973 = 509202

Showing the first eight; more decompositions exist.
