Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61566, here are decompositions:

5 + 61561 = 61566
7 + 61559 = 61566
13 + 61553 = 61566
19 + 61547 = 61566
23 + 61543 = 61566
47 + 61519 = 61566
59 + 61507 = 61566
73 + 61493 = 61566

Showing the first eight; more decompositions exist.
