Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86004, here are decompositions:

5 + 85999 = 86004
13 + 85991 = 86004
71 + 85933 = 86004
73 + 85931 = 86004
101 + 85903 = 86004
151 + 85853 = 86004
157 + 85847 = 86004
167 + 85837 = 86004

Showing the first eight; more decompositions exist.
