Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100566, here are decompositions:

7 + 100559 = 100566
17 + 100549 = 100566
19 + 100547 = 100566
29 + 100537 = 100566
43 + 100523 = 100566
47 + 100519 = 100566
73 + 100493 = 100566
83 + 100483 = 100566

Showing the first eight; more decompositions exist.
