Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67566, here are decompositions:

7 + 67559 = 67566
19 + 67547 = 67566
29 + 67537 = 67566
43 + 67523 = 67566
67 + 67499 = 67566
73 + 67493 = 67566
89 + 67477 = 67566
113 + 67453 = 67566

Showing the first eight; more decompositions exist.
