Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85156, here are decompositions:

23 + 85133 = 85156
47 + 85109 = 85156
53 + 85103 = 85156
107 + 85049 = 85156
179 + 84977 = 85156
347 + 84809 = 85156
419 + 84737 = 85156
443 + 84713 = 85156

Showing the first eight; more decompositions exist.
