Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123534, here are decompositions:

7 + 123527 = 123534
17 + 123517 = 123534
31 + 123503 = 123534
41 + 123493 = 123534
43 + 123491 = 123534
101 + 123433 = 123534
107 + 123427 = 123534
127 + 123407 = 123534

Showing the first eight; more decompositions exist.
