Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581802, here are decompositions:

5 + 581797 = 581802
29 + 581773 = 581802
59 + 581743 = 581802
71 + 581731 = 581802
73 + 581729 = 581802
101 + 581701 = 581802
103 + 581699 = 581802
139 + 581663 = 581802

Showing the first eight; more decompositions exist.
