Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003850, here are decompositions:

31 + 1003819 = 1003850
79 + 1003771 = 1003850
97 + 1003753 = 1003850
103 + 1003747 = 1003850
109 + 1003741 = 1003850
139 + 1003711 = 1003850
157 + 1003693 = 1003850
223 + 1003627 = 1003850

Showing the first eight; more decompositions exist.
