Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56506, here are decompositions:

3 + 56503 = 56506
5 + 56501 = 56506
17 + 56489 = 56506
29 + 56477 = 56506
53 + 56453 = 56506
89 + 56417 = 56506
113 + 56393 = 56506
137 + 56369 = 56506

Showing the first eight; more decompositions exist.
