Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999850, here are decompositions:

41 + 999809 = 999850
101 + 999749 = 999850
167 + 999683 = 999850
179 + 999671 = 999850
197 + 999653 = 999850
227 + 999623 = 999850
239 + 999611 = 999850
251 + 999599 = 999850

Showing the first eight; more decompositions exist.
