Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581950, here are decompositions:

3 + 581947 = 581950
29 + 581921 = 581950
41 + 581909 = 581950
59 + 581891 = 581950
107 + 581843 = 581950
197 + 581753 = 581950
251 + 581699 = 581950
263 + 581687 = 581950

Showing the first eight; more decompositions exist.
