Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999470, here are decompositions:

19 + 999451 = 999470
37 + 999433 = 999470
139 + 999331 = 999470
163 + 999307 = 999470
271 + 999199 = 999470
337 + 999133 = 999470
379 + 999091 = 999470
421 + 999049 = 999470

Showing the first eight; more decompositions exist.
