Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85446, here are decompositions:

7 + 85439 = 85446
17 + 85429 = 85446
19 + 85427 = 85446
83 + 85363 = 85446
113 + 85333 = 85446
149 + 85297 = 85446
199 + 85247 = 85446
223 + 85223 = 85446

Showing the first eight; more decompositions exist.
