Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81534, here are decompositions:

7 + 81527 = 81534
17 + 81517 = 81534
71 + 81463 = 81534
113 + 81421 = 81534
163 + 81371 = 81534
181 + 81353 = 81534
191 + 81343 = 81534
227 + 81307 = 81534

Showing the first eight; more decompositions exist.
