Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85804, here are decompositions:

11 + 85793 = 85804
23 + 85781 = 85804
53 + 85751 = 85804
71 + 85733 = 85804
101 + 85703 = 85804
113 + 85691 = 85804
137 + 85667 = 85804
197 + 85607 = 85804

Showing the first eight; more decompositions exist.
