Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85412, here are decompositions:

31 + 85381 = 85412
43 + 85369 = 85412
79 + 85333 = 85412
109 + 85303 = 85412
199 + 85213 = 85412
211 + 85201 = 85412
331 + 85081 = 85412
421 + 84991 = 85412

Showing the first eight; more decompositions exist.
