Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999378, here are decompositions:

7 + 999371 = 999378
19 + 999359 = 999378
47 + 999331 = 999378
71 + 999307 = 999378
109 + 999269 = 999378
139 + 999239 = 999378
157 + 999221 = 999378
179 + 999199 = 999378

Showing the first eight; more decompositions exist.
