Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509210, here are decompositions:

7 + 509203 = 509210
61 + 509149 = 509210
73 + 509137 = 509210
109 + 509101 = 509210
139 + 509071 = 509210
157 + 509053 = 509210
223 + 508987 = 509210
241 + 508969 = 509210

Showing the first eight; more decompositions exist.
