Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56520, here are decompositions:

11 + 56509 = 56520
17 + 56503 = 56520
19 + 56501 = 56520
31 + 56489 = 56520
41 + 56479 = 56520
43 + 56477 = 56520
47 + 56473 = 56520
53 + 56467 = 56520

Showing the first eight; more decompositions exist.
