Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61506, here are decompositions:

13 + 61493 = 61506
19 + 61487 = 61506
23 + 61483 = 61506
37 + 61469 = 61506
43 + 61463 = 61506
89 + 61417 = 61506
97 + 61409 = 61506
103 + 61403 = 61506

Showing the first eight; more decompositions exist.
