Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513404, here are decompositions:

7 + 513397 = 513404
37 + 513367 = 513404
97 + 513307 = 513404
127 + 513277 = 513404
337 + 513067 = 513404
373 + 513031 = 513404
487 + 512917 = 513404
601 + 512803 = 513404

Showing the first eight; more decompositions exist.
