Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 986842, here are decompositions:

5 + 986837 = 986842
23 + 986819 = 986842
29 + 986813 = 986842
41 + 986801 = 986842
83 + 986759 = 986842
113 + 986729 = 986842
149 + 986693 = 986842
431 + 986411 = 986842

Showing the first eight; more decompositions exist.
