Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999474, here are decompositions:

23 + 999451 = 999474
37 + 999437 = 999474
41 + 999433 = 999474
43 + 999431 = 999474
97 + 999377 = 999474
103 + 999371 = 999474
167 + 999307 = 999474
241 + 999233 = 999474

Showing the first eight; more decompositions exist.
