Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999436, here are decompositions:

3 + 999433 = 999436
5 + 999431 = 999436
47 + 999389 = 999436
59 + 999377 = 999436
107 + 999329 = 999436
149 + 999287 = 999436
167 + 999269 = 999436
197 + 999239 = 999436

Showing the first eight; more decompositions exist.
