Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931842, here are decompositions:

5 + 931837 = 931842
31 + 931811 = 931842
53 + 931789 = 931842
59 + 931783 = 931842
61 + 931781 = 931842
103 + 931739 = 931842
113 + 931729 = 931842
151 + 931691 = 931842

Showing the first eight; more decompositions exist.
