Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999426, here are decompositions:

37 + 999389 = 999426
67 + 999359 = 999426
97 + 999329 = 999426
139 + 999287 = 999426
157 + 999269 = 999426
193 + 999233 = 999426
227 + 999199 = 999426
257 + 999169 = 999426

Showing the first eight; more decompositions exist.
