Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529940, here are decompositions:

7 + 529933 = 529940
13 + 529927 = 529940
127 + 529813 = 529940
193 + 529747 = 529940
199 + 529741 = 529940
283 + 529657 = 529940
337 + 529603 = 529940
409 + 529531 = 529940

Showing the first eight; more decompositions exist.
