Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85820, here are decompositions:

3 + 85817 = 85820
103 + 85717 = 85820
109 + 85711 = 85820
151 + 85669 = 85820
181 + 85639 = 85820
193 + 85627 = 85820
199 + 85621 = 85820
223 + 85597 = 85820

Showing the first eight; more decompositions exist.
