Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999418, here are decompositions:

29 + 999389 = 999418
41 + 999377 = 999418
47 + 999371 = 999418
59 + 999359 = 999418
89 + 999329 = 999418
131 + 999287 = 999418
149 + 999269 = 999418
179 + 999239 = 999418

Showing the first eight; more decompositions exist.
