Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521460, here are decompositions:

13 + 521447 = 521460
31 + 521429 = 521460
59 + 521401 = 521460
61 + 521399 = 521460
67 + 521393 = 521460
83 + 521377 = 521460
97 + 521363 = 521460
101 + 521359 = 521460

Showing the first eight; more decompositions exist.
