Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999412, here are decompositions:

23 + 999389 = 999412
41 + 999371 = 999412
53 + 999359 = 999412
83 + 999329 = 999412
173 + 999239 = 999412
179 + 999233 = 999412
191 + 999221 = 999412
263 + 999149 = 999412

Showing the first eight; more decompositions exist.
