Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18534, here are decompositions:

11 + 18523 = 18534
13 + 18521 = 18534
17 + 18517 = 18534
31 + 18503 = 18534
41 + 18493 = 18534
53 + 18481 = 18534
73 + 18461 = 18534
83 + 18451 = 18534

Showing the first eight; more decompositions exist.
