Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581784, here are decompositions:

11 + 581773 = 581784
17 + 581767 = 581784
31 + 581753 = 581784
41 + 581743 = 581784
53 + 581731 = 581784
83 + 581701 = 581784
97 + 581687 = 581784
101 + 581683 = 581784

Showing the first eight; more decompositions exist.
