Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513754, here are decompositions:

5 + 513749 = 513754
23 + 513731 = 513754
71 + 513683 = 513754
113 + 513641 = 513754
281 + 513473 = 513754
347 + 513407 = 513754
383 + 513371 = 513754
401 + 513353 = 513754

Showing the first eight; more decompositions exist.
