Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943842, here are decompositions:

5 + 943837 = 943842
23 + 943819 = 943842
41 + 943801 = 943842
43 + 943799 = 943842
59 + 943783 = 943842
61 + 943781 = 943842
73 + 943769 = 943842
79 + 943763 = 943842

Showing the first eight; more decompositions exist.
