Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999618, here are decompositions:

5 + 999613 = 999618
7 + 999611 = 999618
19 + 999599 = 999618
89 + 999529 = 999618
97 + 999521 = 999618
127 + 999491 = 999618
167 + 999451 = 999618
181 + 999437 = 999618

Showing the first eight; more decompositions exist.
