Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999230, here are decompositions:

13 + 999217 = 999230
31 + 999199 = 999230
61 + 999169 = 999230
97 + 999133 = 999230
139 + 999091 = 999230
163 + 999067 = 999230
181 + 999049 = 999230
223 + 999007 = 999230

Showing the first eight; more decompositions exist.
