Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985842, here are decompositions:

23 + 985819 = 985842
43 + 985799 = 985842
59 + 985783 = 985842
61 + 985781 = 985842
83 + 985759 = 985842
101 + 985741 = 985842
113 + 985729 = 985842
139 + 985703 = 985842

Showing the first eight; more decompositions exist.
