Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520430, here are decompositions:

3 + 520427 = 520430
7 + 520423 = 520430
19 + 520411 = 520430
37 + 520393 = 520430
61 + 520369 = 520430
67 + 520363 = 520430
73 + 520357 = 520430
139 + 520291 = 520430

Showing the first eight; more decompositions exist.
