Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988842, here are decompositions:

5 + 988837 = 988842
13 + 988829 = 988842
53 + 988789 = 988842
59 + 988783 = 988842
79 + 988763 = 988842
83 + 988759 = 988842
109 + 988733 = 988842
131 + 988711 = 988842

Showing the first eight; more decompositions exist.
