Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85406, here are decompositions:

37 + 85369 = 85406
43 + 85363 = 85406
73 + 85333 = 85406
103 + 85303 = 85406
109 + 85297 = 85406
163 + 85243 = 85406
193 + 85213 = 85406
313 + 85093 = 85406

Showing the first eight; more decompositions exist.
