Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999236, here are decompositions:

3 + 999233 = 999236
19 + 999217 = 999236
37 + 999199 = 999236
67 + 999169 = 999236
103 + 999133 = 999236
193 + 999043 = 999236
229 + 999007 = 999236
379 + 998857 = 999236

Showing the first eight; more decompositions exist.
