Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705436, here are decompositions:

7 + 8705429 = 8705436
17 + 8705419 = 8705436
37 + 8705399 = 8705436
53 + 8705383 = 8705436
67 + 8705369 = 8705436
137 + 8705299 = 8705436
139 + 8705297 = 8705436
167 + 8705269 = 8705436

Showing the first eight; more decompositions exist.
