Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61530, here are decompositions:

11 + 61519 = 61530
19 + 61511 = 61530
23 + 61507 = 61530
37 + 61493 = 61530
43 + 61487 = 61530
47 + 61483 = 61530
59 + 61471 = 61530
61 + 61469 = 61530

Showing the first eight; more decompositions exist.
