Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85700, here are decompositions:

31 + 85669 = 85700
61 + 85639 = 85700
73 + 85627 = 85700
79 + 85621 = 85700
103 + 85597 = 85700
151 + 85549 = 85700
271 + 85429 = 85700
331 + 85369 = 85700

Showing the first eight; more decompositions exist.
