Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581926, here are decompositions:

5 + 581921 = 581926
17 + 581909 = 581926
53 + 581873 = 581926
83 + 581843 = 581926
173 + 581753 = 581926
197 + 581729 = 581926
227 + 581699 = 581926
239 + 581687 = 581926

Showing the first eight; more decompositions exist.
