Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175842, here are decompositions:

5 + 175837 = 175842
13 + 175829 = 175842
31 + 175811 = 175842
59 + 175783 = 175842
61 + 175781 = 175842
83 + 175759 = 175842
89 + 175753 = 175842
151 + 175691 = 175842

Showing the first eight; more decompositions exist.
