Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999486, here are decompositions:

53 + 999433 = 999486
97 + 999389 = 999486
109 + 999377 = 999486
127 + 999359 = 999486
157 + 999329 = 999486
179 + 999307 = 999486
199 + 999287 = 999486
269 + 999217 = 999486

Showing the first eight; more decompositions exist.
