Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520480, here are decompositions:

29 + 520451 = 520480
47 + 520433 = 520480
53 + 520427 = 520480
71 + 520409 = 520480
101 + 520379 = 520480
131 + 520349 = 520480
167 + 520313 = 520480
173 + 520307 = 520480

Showing the first eight; more decompositions exist.
