Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581964, here are decompositions:

11 + 581953 = 581964
17 + 581947 = 581964
23 + 581941 = 581964
43 + 581921 = 581964
73 + 581891 = 581964
101 + 581863 = 581964
107 + 581857 = 581964
167 + 581797 = 581964

Showing the first eight; more decompositions exist.
