Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85464, here are decompositions:

11 + 85453 = 85464
13 + 85451 = 85464
17 + 85447 = 85464
37 + 85427 = 85464
53 + 85411 = 85464
83 + 85381 = 85464
101 + 85363 = 85464
103 + 85361 = 85464

Showing the first eight; more decompositions exist.
