Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509546, here are decompositions:

3 + 509543 = 509546
97 + 509449 = 509546
157 + 509389 = 509546
229 + 509317 = 509546
283 + 509263 = 509546
307 + 509239 = 509546
397 + 509149 = 509546
409 + 509137 = 509546

Showing the first eight; more decompositions exist.
