Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37842, here are decompositions:

11 + 37831 = 37842
29 + 37813 = 37842
31 + 37811 = 37842
43 + 37799 = 37842
59 + 37783 = 37842
61 + 37781 = 37842
149 + 37693 = 37842
151 + 37691 = 37842

Showing the first eight; more decompositions exist.
