Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76566, here are decompositions:

5 + 76561 = 76566
23 + 76543 = 76566
29 + 76537 = 76566
47 + 76519 = 76566
59 + 76507 = 76566
73 + 76493 = 76566
79 + 76487 = 76566
103 + 76463 = 76566

Showing the first eight; more decompositions exist.
