Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19672, here are decompositions:

11 + 19661 = 19672
89 + 19583 = 19672
101 + 19571 = 19672
113 + 19559 = 19672
131 + 19541 = 19672
239 + 19433 = 19672
251 + 19421 = 19672
269 + 19403 = 19672

Showing the first eight; more decompositions exist.
