Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61584, here are decompositions:

23 + 61561 = 61584
31 + 61553 = 61584
37 + 61547 = 61584
41 + 61543 = 61584
73 + 61511 = 61584
97 + 61487 = 61584
101 + 61483 = 61584
113 + 61471 = 61584

Showing the first eight; more decompositions exist.
