Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999500, here are decompositions:

67 + 999433 = 999500
193 + 999307 = 999500
283 + 999217 = 999500
331 + 999169 = 999500
367 + 999133 = 999500
409 + 999091 = 999500
433 + 999067 = 999500
457 + 999043 = 999500

Showing the first eight; more decompositions exist.
