Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85730, here are decompositions:

13 + 85717 = 85730
19 + 85711 = 85730
61 + 85669 = 85730
103 + 85627 = 85730
109 + 85621 = 85730
181 + 85549 = 85730
199 + 85531 = 85730
277 + 85453 = 85730

Showing the first eight; more decompositions exist.
