Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19654, here are decompositions:

71 + 19583 = 19654
83 + 19571 = 19654
101 + 19553 = 19654
113 + 19541 = 19654
191 + 19463 = 19654
197 + 19457 = 19654
227 + 19427 = 19654
233 + 19421 = 19654

Showing the first eight; more decompositions exist.
