Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156042, here are decompositions:

23 + 156019 = 156042
31 + 156011 = 156042
149 + 155893 = 156042
151 + 155891 = 156042
179 + 155863 = 156042
181 + 155861 = 156042
191 + 155851 = 156042
193 + 155849 = 156042

Showing the first eight; more decompositions exist.
