Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999562, here are decompositions:

41 + 999521 = 999562
71 + 999491 = 999562
131 + 999431 = 999562
173 + 999389 = 999562
191 + 999371 = 999562
233 + 999329 = 999562
293 + 999269 = 999562
461 + 999101 = 999562

Showing the first eight; more decompositions exist.
