Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983890, here are decompositions:

29 + 983861 = 983890
41 + 983849 = 983890
71 + 983819 = 983890
101 + 983789 = 983890
107 + 983783 = 983890
113 + 983777 = 983890
191 + 983699 = 983890
293 + 983597 = 983890

Showing the first eight; more decompositions exist.
