Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85670, here are decompositions:

3 + 85667 = 85670
31 + 85639 = 85670
43 + 85627 = 85670
73 + 85597 = 85670
139 + 85531 = 85670
157 + 85513 = 85670
223 + 85447 = 85670
241 + 85429 = 85670

Showing the first eight; more decompositions exist.
