Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85418, here are decompositions:

7 + 85411 = 85418
37 + 85381 = 85418
181 + 85237 = 85418
271 + 85147 = 85418
331 + 85087 = 85418
337 + 85081 = 85418
397 + 85021 = 85418
409 + 85009 = 85418

Showing the first eight; more decompositions exist.
