Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172982, here are decompositions:

13 + 172969 = 172982
181 + 172801 = 172982
223 + 172759 = 172982
241 + 172741 = 172982
349 + 172633 = 172982
379 + 172603 = 172982
409 + 172573 = 172982
421 + 172561 = 172982

Showing the first eight; more decompositions exist.
