Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999778, here are decompositions:

5 + 999773 = 999778
29 + 999749 = 999778
107 + 999671 = 999778
167 + 999611 = 999778
179 + 999599 = 999778
257 + 999521 = 999778
347 + 999431 = 999778
389 + 999389 = 999778

Showing the first eight; more decompositions exist.
