Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581956, here are decompositions:

3 + 581953 = 581956
47 + 581909 = 581956
83 + 581873 = 581956
113 + 581843 = 581956
227 + 581729 = 581956
257 + 581699 = 581956
269 + 581687 = 581956
293 + 581663 = 581956

Showing the first eight; more decompositions exist.
