Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513628, here are decompositions:

149 + 513479 = 513628
197 + 513431 = 513628
257 + 513371 = 513628
281 + 513347 = 513628
317 + 513311 = 513628
359 + 513269 = 513628
389 + 513239 = 513628
461 + 513167 = 513628

Showing the first eight; more decompositions exist.
